Synthesis, structure and catalysis of a NHC-Pd(II) complex based on a tetradentate mixed ligand

Bis-benzimidazolium salt (S)-2,2?-bis[2??-(N-picolyl-benzimidazoliumyl)ethoxy]-1,1?-binaphthyl hexafluorophosphate [(S)-LH2]¡¤(PF6)2 and its NHC palladium(ii) complex [(S)-LPd](PF6)2 (1) have been prepared and characterized. Complex 1 is formed by one tetradentate mixed ligand (S)-L and one Pd(ii) ion, in which one 15-membered ring and two 6-membered rings are present. In this complex, intramolecular pi-pi interactions between naphthalene rings and benzimidazole rings are observed. Additionally, the catalytic activity of complex 1 in three types of C-C coupling reactions (Suzuki-Miyaura, Heck-Mizoroki and Sonogashira reactions) was investigated. The results show that complex 1 is an effective catalyst in these coupling reactions.

Effects of organo-clay and sodium dodecyl sulfonate intercalated layered double hydroxide on thermal and flame behaviour of intumescent flame retarded polypropylene

The thermal and flame performances of intumescent flame retarded polypropylene (PP/IFR) composites with organically modified clay or sodium dodecyl sulfonate intercalated layered double hydroxide (SDS-LDH) were studied. The organo-clay particles were partially exfoliated in the PP matrix, while intercalation and aggregation was obtained for SDS-LDH. Incorporation of SDS-LDH improved the thermal stability and flame retardancy of the intumescent flame retarded PP composite in the early stage of heating and combustion; while the effects of organo-clay came into play in the middle-later stage. Differences in degradation pathway of clay and LDH were responsible for the above phenomenon which bore important implication for the barrier mechanism. The introduction of organo-clay into PP/IFR not only increased the char residue, but also formed compact and folded morphology of char residue which provided more effective protect for underlying materials against heat and oxygen relative to LDH, thus improved the flame retardancy of intumescent flame retarded PP samples more efficiently.

Highly Z-selective metathesis homocoupling of terminal olefins

(Chemical Equation Presented) Mo and W MonoAryloxide-Pyrrolide (MAP) olefin metathesis catalysts can couple terminal olefins to give as high as >98% Z-products in moderate to high yields with as little as 0.2% catalyst. Results are reported for 1-hexene, 1-octene, allylbenzene, allyltrimethylsilane, methyl-10-undecenoate, methyl-9-decenoate, allylB(pinacolate), allylOBenzyl, allylNHTosyl, and allylNHPh. It is proposed that high Z-selectivity is achieved because a large aryloxide only allows metallacyclobutanes to form that contain adjacent cis substituents and because isomerization of Z-product to E-product can be slow in that same steric environment.

Synthesis of axially chiral gold complexes and their applications in asymmetric catalyses

Several novel chiral N-heterocyclic carbene and phosphine ligands were prepared from (S)-BINOL. Moreover, their ligated Au complexes were also successfully synthesized and characterized by X-ray crystal diffraction. A weak gold-pi interaction between the Au atom and the aromatic ring in these gold complexes was identified. Furthermore, we confirmed the formation of a pair of diastereomeric isomers in NHC gold complexes bearing an axially chiral binaphthyl moiety derived from the hindered rotation around C-C and C-N bonds. In the asymmetric intramolecular hydroamination reaction most of these chiral Au(I) complexes showed good catalytic activities towards olefins tethered with a NHTs functional group to give the corresponding product in moderate yields and up to 29% ee.

Reversible addition-fragmentation chain transfer polymerization of acrylonitrile under irradiation of blue LED light

Compared to unhealthy UV or gamma -ray and high-energy-consumption thermal external stimuli, the promising light emitting diode (LED) external stimulus has some outstanding technological merits such as narrow wavelength distribution, low heat generation and energy consumption, and safety for human beings. In this work, a novel reversible addition-fragmentation transfer (RAFT) polymerization system for acrylonitrile (AN) was developed under the irradiation of blue LED light at room temperature, using 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) as a novel radical initiator and 2-cyanoprop-2-yl-1-dithionaphthalate (CPDN) as the typical chain transfer agent. Well-defined polyacrylonitrile (PAN) with a controlled molecular weight and narrow molecular weight distribution was successfully synthesized. This strategy may provide another effective method for scientific researchers or the industrial community to synthesize a PAN-based precursor of carbon fibers.

Oxidovanadium catechol complexes: Radical versus non-radical states and redox series

A new family of oxidovanadium complexes, [(L1 R)(VO)(LR?)] (R = H, R? = H, 1; R = H, R? = -CMe3, 2; R = H, R? = Me, 3; R = -CMe3, R? = H, 4 and R = -CMe3, R? = -CMe3, 5), incorporating tridentate L1RH ligands (L1 RH = 2,4-di-R-6-{(2-(pyridin-2-yl)hydrazono)methyl}phenol) and substituted catechols (LR?H2) was substantiated. The V-Ophenolato (cis to V=O), V-OCAT (cis to V=O) and V-OCAT (trans to V=O) lengths span the ranges, 1.894(2)-1.910(2), 1.868(2)-1.887(2), and 2.120(2)-2.180(2) A. The metrical oxidation states (MOS) of the catechols in 1-5 are fractional and vary from -1.43 to -1.60. The 51V isotropic chemical shifts of solids and solutions of 1-5 are deshielded (51V CP MAS: -19.8 to +248.6; DMSO-d6: +173.9 to +414.55 ppm). The closed shell singlet (CSS) solutions of 1-5 are unstable due to open shell singlet (OSS) perturbations. The ground electronic states of 1-5 are defined by the resonance contribution of the catecholates (L R?CAT2-) and LR? SQ-? coordinated to the [VO]3+ and [VO]2+ ions. 1-5 are reversibly reducible by one electron at -(0.58-0.87) V, referenced vs ferrocenium/ferrocene, to VO2+ complexes, [(L1R-)(VO2+)(L R?CAT2-)]- [1-5]-. 1-5 display another quasi-reversible or irreversible reduction wave at -(0.80-1.32) V due to the formation of hydrazone anion radical (L 1R2-?) complexes, [(L1 R2-?)(VO2+)(LR?CAT 2-)]2-, [1-5]2-, with S = 1 authenticated by the unrestricted density functional theory (DFT) calculations on 12- and 32- ions. Frozen glasses electron paramagnetic resonance (EPR) spectra of [1-5]- ions [e.g., for 2, g|| = 1.948, g = 1.979, A|| = 164, A = 60] affirmed that [1-5]- ions are the [VO]2+ complexes of LR?CAT 2-. Spectro-electrochemical measurements and time-dependent DFT (TD DFT) calculations on 1, 3, 1-, 3-, and 12- disclosed that the near infrared (NIR) absorption bands of 1-5 at 800 nm are due to the CSS-OSS metal to ligand charge transfer which are red-shifted in the solid state and disappear in [1-5]- and [1-5]2- ions.

Mechanism of water exchange on five-coordinate copper(II) complexes

The effects of temperature and pressure on the water exchange reaction of the five-coordinate complexes [Cu(tmpa)(H2O)]2+ and [Cu(fz2(H2O)]2- (tmpa = tris(2-pyridylmethyl)amine; fz= ferrozine = 5,6-bis(4-sulfonatophenyl)-3-(2-pyridyl)-1,2,4-triazine) were studied by employing 17O NMR spectroscopy. The former compound shows a solvent exchange rate constant kexof (8.6 ¡À 0.4) ¡Á 106 s-1 at 298 K and ambient pressure, within a factor of three of that for the corresponding process for [Cu(tren)(H2O)]2+ (tren = 2,2?,2?-triaminotriethylamine). The activation parameters DeltaH# DeltaS# and DeltaV# for the reaction are 43.0 ¡À 1.5 kJ mol-1, +32 ¡À 6 J K -1 mol-1 and -3.0 ¡À 0.1 cm3 mol-1, respectively. For [Cu(fz)2(H2O)]2-, Kex is (3.5 ¡À 2.6) ¡Á 105 s-1 at 298 K and ambient pressure, which is about an order of magnitude less than for [Cu(tren)(H2O)]2+. The DeltaH#,DeltaS# and DeltaV# values for the water exchange are 25.9 ¡À 2.2 KJ mol-1, -52 ¡À 7 J K -1 mol -1 and -4.7 ¡À 0.2 cm3mol-1 The activation volume is modestly negative for both reactions and therefore implies an associative interchange (Ia) mechanism. The results are discussed in reference to data for water exchange reactions of Cu(II) complexes available from the literature.
