Enhanced water splitting through different substituted cobalt-salophen electrocatalysts

Synthesis of stable catalysts for water splitting is important for the renewable and clean energy production. Here, water oxidation activities of cobalt (II) complexes CoL1-CoL3 (1-3) with salophen type ligands (N,N’-bis(salicylidene)-4-chloro-1,2-phenylendiamine (H2L1), N,N’-bis(salicylidene)-4-bromo-1,2-phenylendiamine (H2L2) and N,N’-bis(salicylidene)-4-nitro-1,2-phenylendiamine (H2L3)) are studied by electrochemical techniques, FE-SEM images and XRD patterns. Linear sweep voltammetry studies indicate that 2 and 3 have superior activities and only require the overpotential of 316 and 247 mV vs. RHE at current density of 10 mA/cm(2) with Tafel slopes of 75 and 50 mVdec(-1) at pH = 11. Experiments show relationships between the stability of the complexes and their catalytic activity. It is revealed that substituents on ligands affect the catalytic behaviors. Experiments show that in the presence of 2 and 3, the complexed cobalt ions are likely candidates as molecular catalysts for water oxidation. It is speculated that the O-O bond formation occurs by oxidizing the active center of cobalt complexes. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.

P,N,O type chiral imino- and aminophosphine ligands and their applications in Ru(II)-catalyzed asymmetric transfer hydrogen reactions

Chiral P,N,O type imino- (1a-d) and aminophosphine ligands (2a-d), substituted with methyl-, isopropyl-, phenyl- and benzyl groups, were synthesized and characterized by spectroscopic techniques such as NMR, FTIR and HRMS. The structure of the ligand 1c was also determined by single crystal X-ray diffraction analysis. The X-ray data revealed that compound 1c exhibited triclinic-P1 space group with C40H34NOP molecular formula. The catalytic performances of these imino- and aminophosphine ligands were tested in ruthenium catalyzed asymmetric transfer hydrogenation of aromatic ketones in 2-propanol. Ruthenium(II) complexes were generated in situ from Ru(cod)Cl-2, Ru(dmso)(4)Cl-2, Ru(PPh3)(3)Cl-2 and [Ru(p-cymene)Cl-2](2) precursors. According to the chromatographic analyses, isopropyl- substituted chiral aminophosphine ligand 2-((2-(diphenylphosphinyl)benzyl) amino)-3-methyl-1,1-diphenylbutan-1-ol (2b) and [Ru(cod)Cl-2] combination were found to be the best catalyst system, affording (R)-enriched 1-(4-bromophenyl)ethanol in 85% ee and 98% conversion.

Pd(5%)-KIT-6, Pd(5%)-SBA-15 and Pd(5%)-SBA-16 catalysts in water extract of pomegranate ash: A case study in heterogenization of Suzuki-Miyaura reaction under external base and ligand free conditions

Real heterogenization of Suzuki-Miyaura cross-coupling (SMC) is arduous quest owing to unavoidable homogeneous mechanism of heterogeneous catalysts. This article reports a study of heterogenization of SMC using mesoporous silica supported Pd-nanoparticles (Pd-NPs) under ligand and external base free conditions. Pdmesoporous silica catalysts such as Pd-KIT-6, Pd (5%)-SBA-16 and Pd (5%)-SBA-15 were synthesized and studied for SMC in water extract of pomegranate ash (WEPA). Pd (5%)-KIT-6 was the best amongst, and successful reusability of Pd (5%)-KIT-6 and hot-filtration experiments indicated its high stability, conveys pure heterogenous mechanism over inevitable homogenous mechanism. The large choice of substrates, high stability of the catalyst in green and renewable medium & base systems, and absence of ligands are the luminary potencies of this inquest.

Current application of MOFs based heterogeneous catalysts in catalyzing transesterification/esterification for biodiesel production: A review

Biodiesel is a green and renewable energy, which is supposed to be a promising substitute to fossil diesel. Normally, biodiesel is produced via transesterification/esterification with assistance of homogeneous or heterogeneous catalyst. However, homogeneous catalyst cannot be recovered and reused. In particular, the downstream purification is needed resulting in large number of wastewater. Thereby, heterogeneous catalysts are put forward to address these above problems. The catalytic activity of heterogeneous catalyst (alkaline, acid, and enzyme) is restricted by the active site dispersity, available active site amount, and catalytic stability. With regard to this, supporting active site on carrier is a feasible technology to improve catalytic performance. Metal organic frameworks (MOFs) are a special class of coordination polymers, which are self-assembled by metal ion and organic ligand with topological structure. The promising merits of huge porosity, uniform pore size, controllable functional groups, and structural tenability of MOFs are highly desirable in synthesizing catalyst for transesterification/esterification. This paper reviews the current application of MOFs in catalyzing transesterification/esterification, which is involved with catalytic mechanism, MOFs types, especially the MOFs catalyst and MOFs derivate based catalysts. Meanwhile, the reusability of MOFs based catalyst are further analyzed. Thereafter, the effect of transesterification/esterification parameters on catalytic performance are comprehensively summarized. The future perspectives for MOFs application in biodiesel production are also discussed.

Study of H(2)AzTO-based energetic metal-organic frameworks for catalyzing the thermal decomposition of ammonium perchlorate

High-energy metal-organic frameworks (E-MOFs) are very promising as catalysts with providing both energy and catalyzing. 5,5′-Azotetrazole-1,1′-diol (H(2)AzTO) is chosen as ligand due to its high energy properties. In this work, four metal complexes with high energy and low sensitivity based on H(2)AzTO with non-heavy metals cations Co (II), Cd (II), Ni (II), and Cu (II) were synthesized. Differential scanning calorimetry and thermogravimetry analyses revealed that compound 2 had excellent thermal stability. The mechanical sensitivities and detonation performances of compounds 1-4 were also analyzed in detail, and results indicated those compounds have sluggish sensitivity and wonderful detonation performances. The results of the catalytic thermal decomposition of AP by compound 1-4 show that compound 4 has application prospects as a high-energy AP catalyst.

Nickel-Catalyzed N-Arylation of Fluoroalkylamines

The Ni-catalyzed N-arylation of beta-fluoroalkylamines with broad scope is reported for the first time. Use of the air-stable pre-catalyst (PAd2-DalPhos)Ni(o-tol)Cl allows for reactions to be conducted at room temperature (25 degrees C, NaOtBu), or by use of a commercially available dual-base system (100 degrees C, DBU/NaOTf), to circumvent decomposition of the N-(beta-fluoroalkyl)aniline product. The mild protocols disclosed herein feature broad (hetero)aryl (pseudo)halide scope (X=Cl, Br, I, and for the first time phenol-derived electrophiles), encompassing base-sensitive substrates and enantioretentive transformations, in a manner that is unmatched by any previously reported catalyst system.

Efficient MO Dye Degradation Catalyst of Cu(I)-Based Coordination Complex from Dissolution-Recrystallization Structural Transformation

Methyl orange (MO) is a main organic water pollutants that has been attracted a lot of attention; it can be degraded under photoirradiation in the presence of H2O2. Herein, we developed two Cu(I)-based coordination complexes (named H-2(Cu4Br6)[(Cu4Br3)(TTTMB)(2)(H2O)](2) (ZZY-2) and (Cu5Br6)(Cu6Br9)[Cu3Br(TTTMB)2] (ZZY-3)), which could degrade the MO dye in the presence of H2O2 with or without photoirradiation (TTTMB = 1,3,5-tris(1,2,4-triazol-1-ylmethyl)-2,4,6-trimethylbenzene). Three-dimensional (3D) frameworks ZZY-2 and ZZY-3 were based on the molecule cage [Cu-3(TTTMB)(2)] with the homochiral (-CuBrCu-)n triple-stranded helical chain and multinuclear Cu5Br6 and Cu6Br9 units, respectively, which could be obtained via the dissolutionrecrystallization structural transformation (DRST) from two-dimensional (2D) network ZZY-1 ([Cu-3(TTTMB)(2)(H2O)(6)Cl-6]center dot 2H(2)O). The addition of CuBr2 and the amount of HCOOH were decisive for the DRST, where the formation of a CuN coordination bond between the free 2-positional nitrogen atom and Cu(II) was the initiator for DRST. ZZY-2 and ZZY-3 had superior chemical stability, which could maintain the structures after three cycles of degradation reactions. MO degradation catalyzed by ZZY-2 and ZZY-3 could undergo a Fenton-like reaction to produce the active species OH in the presence of H2O2. No requirement of photoirradiation for ZZY-2 and ZZY-3 to degrade MO provided more practical meaning to sewage treatment. Cu(II)-based ZZY-4 was also obtained as ZZY-1 in the presence of HNO3, which demonstrated the influence of acid on the structure of nitrogen-based ligands. ZZY-4 has shown no capacity to degrade MO, which indicated that the oxidation of Cu(I) by H2O2 could be the key step to initiate the MO degradation.

(3S,4S)-N-substituted-3,4-dihydroxypyrrolidines as ligands for the enantioselective Henry reaction

The enantioselective Henry reaction is a very important and useful carbon-carbon bond forming reaction. The execution of this reaction requires the use of efficient chiral catalysts. In this work, in situ formed complexes of N-substituted dihydroxypyrrolidines, chiral ligands derived from L-tartaric acid and amines, were evaluated as catalysts in the enantioselective Henry reaction. The results showed that the nature of the N-substituent on the ligand significantly influences the outcome of the reaction. Best results were obtained using a Cu (II) complex of (3S,4S)-N-benzyl-3,4-dihydroxypyrrolidine, in the presence of DIPEA, for the reaction of aromatic aldehydes with nitromethane, at room temperature, originating products with er up to 92:8 (R:S) and conversions up to 96%. The interaction between the pyrrolidine ligand and the copper ion, in isopropanol, was followed by UV-vis spectrophotometry, showing a 1:1 stoichiometry and a binding constant of 4.4. The results obtained will contribute to the design and development of more efficient chiral catalysts for this type of reaction.

C1-Symmetric PNP Ligands for Manganese-Catalyzed Enantioselective Hydrogenation of Ketones: Reaction Scope and Enantioinduction Model

A family of ferrocene-based chiral PNP ligands is reported. These tridentate ligands were successfully applied in Mn- catalyzed asymmetric hydrogenation of ketones, giving high enantioselectivities (92%similar to 99% ee for aryl alkyl ketones) as well as high efficiencies (TON up to 2000). In additiondialkyl ketones could also be hydrogenated smoothly. Manganese intermediates that might be involved in the catalytic cycle were analyzed. DFT calculation was carried out to help understand the chiral induction model. The Mn/PNP catalyst could discriminate two groups with different steric properties by deformation of the phosphine moiety in the flexible 5-membered ring.

Rhodium Complexes in P-C Bond Formation: Key Role of a Hydrido Ligand

Olefin hydrophosphanation is an attractive route for the atom-economical synthesis of functionalized phosphanes. This reaction involves the formation of P-C and H-C bonds. Thus, complexes that contain both hydrido and phosphanido functionalities are of great interest for the development of effective and fast catalysts. Herein, we showcase the excellent activity of one of them, [Rh(Tp)H(PMe3)(PPh2)] (1), in the hydrophosphanation of a wide range of olefins. In addition to the required nucleophilicity of the phosphanido moiety to accomplish the P-C bond formation, the key role of the hydride ligand in 1 has been disclosed by both experimental results and DFT calculations. An additional Rh-H center dot center dot center dot C stabilization in some intermediates or transition states favors the hydrogen transfer reaction from rhodium to carbon to form the H-C bond. Further support for our proposal arises from the poor activity exhibited by the related chloride complex [Rh(Tp)Cl(PMe3)(PPh2)] as well as from stoichiometric and kinetic studies.
