An enantioselective and branch-regioselective α-allylation of N-Me anilines with allylic acetates under dual palladium/photoredox catalysis was described. Readily available N-Me anilines were used as formal ”hard” alkyl nucleophiles without preactivation. Acetic acid was the only side product, which led to a high atom economy of this reaction. This protocol showed good functional group tolerance and broad scope. A range of chiral homoallylic amines I [R = Me, i-Pr, Ph, etc.; Ar1 = Ph, 4-MeOC6H4, 4-NHAcC6H4, etc.; Ar2 = Ph, 3-MeC6H4, 4-ClC6H4, etc.] were prepared in moderate to good yields (up to 76%) and excellent regioselectivities (B:L > 95:5 in all cases) and enantioselectivities (up to 96% ee) under mild reaction conditions.

The article conveys some information:

The preparation and characterization of a novel three-dimensional organic material consisting of porphyrin arrays on carbon nanotubes embedded in an organogel is reported. Firstly, the porphyrin array was prepared through metal-ligand coordination of a ditopic ligand (1,2-bis(4-pyridyl)ethane) and two bis-Zn(II) porphyrins, linked through a pyrene core, and was studied through UV-Vis, NMR and diffusion spectroscopies. Secondly, the porphyrin supramol. architecture was adsorbed on pristine carbon nanotubes, greatly improving the dispersibility of the latter in organic solvents. The hybrid material was characterised by means of UV-Vis spectroscopy, microscopic techniques and thermogravimetric anal. Finally, by exploiting the anisotropic magnetic susceptibility of carbon nanotubes, the hybrid material was aligned under a magnetic field, the organization of which could be maintained by in situ gelation. The resultant hybrid organogel exhibited notable optical anisotropy, suggesting an anisotropic arrangement of the porphyrin-CNTs architectures in the macroscopic material.

Luo, Xuyi; Shen, Hongguang; Perera, Kuluni; Tran, Dung Trong; Boudouris, Bryan W.; Mei, Jianguo published their research in ACS Macro Letters in 2021. The article was titled 《Designing Donor-Acceptor Copolymers for Stable and High-Performance Organic Electrochemical Transistors》.Safety of Tris(dibenzylideneacetone)dipalladium(0) The article contains the following contents:

Organic electrochem. transistors (OECTs) are oft-used for bioelectronic applications, and a variety of OECT channel materials have been developed in recent years. However, the majority of these materials are still limited by long-term performance and stability challenges. To resolve these issues, we implemented a next-generation design of polymers for OECTs. Specifically, diketopyrrolopyrrole (DPP) building blocks were copolymerized with propylene dioxythiophene-based (Pro-based) monomers to create a donor-acceptor-type conjugated polymer (PProDOT-DPP). These PProDOT-DPP macromols. were synthesized using a straightforward direct arylation polymerization synthetic route. The PProDOT-DPP polymer thin film exhibited excellent electrochem. response, low oxidation potential, and high crystallinity, as evidenced by spectroelectrochem. measurements and grazing incidence wide-angle X-ray scattering measurements. Thus, the resultant polymer thin films had high charge mobility and volumetric capacitance values (i.e., μC* as high as 310 F cm-1 V-1 s-1) when they were used as the active layer materials in OECT devices, which places PProDOT-DPP among the highest performing accumulation-mode OECT polymers reported to date. The performance of the PProDOT-DPP thin films was also retained for 100 cycles and over 2000 s of ON-OFF cycling, indicating the robust stability of the materials. Therefore, this effort provides a clear roadmap for the design of electrochem. active macromols. for accumulation-mode OECTs, where crystalline acceptor cores are incorporated into an all-donor polymer. We anticipate that this will ultimately inspire future polymer designs to enable OECTs with both high elec. performance and operational stability.

Recommanded Product: Tris(dibenzylideneacetone)dipalladium(0)In 2020 ,《RBC membrane camouflaged semiconducting polymer nanoparticles for near-infrared photoacoustic imaging and photothermal therapy》 was published in Nano-Micro Letters. The article was written by Zheng, Dongye; Yu, Peiwen; Wei, Zuwu; Zhong, Cheng; Wu, Ming; Liu, Xiaolong. The article contains the following contents:

Semiconducting conjugated polymer nanoparticles (SPNs) represent an emerging class of phototheranostic materials with great promise for cancer treatment. In this report, low-bandgap electron donor-acceptor (D-A)-conjugated SPNs with surface cloaked by red blood cell membrane (RBCM) are developed for highly effective photoacoustic imaging and photothermal therapy. The resulting RBCM-coated SPN (SPN@RBCM) displays remarkable near-IR light absorption and good photostability, as well as high photothermal conversion efficiency for photoacoustic imaging and photothermal therapy. Particularly, due to the small size (< 5 nm), SPN@RBCM has the advantages of deep tumor penetration and rapid clearance from the body with no appreciable toxicity. The RBCM endows the SPNs with prolonged systematic circulation time, less reticuloendothelial system uptake and reduced immune-recognition, hence improving tumor accumulation after i.v. injection, which provides strong photoacoustic signals and exerts excellent photothermal therapeutic effects. Thus, this work provides a valuable paradigm for safe and highly efficient tumor photoacoustic imaging and photothermal therapy for further clin. translation.

《Structure and activity of supported bimetallic NiPd nanoparticles: influence of preparation method on CO2 reduction》 was written by Braga, Adriano H.; Costa, Natalia J. S.; Philippot, Karine; Goncalves, Renato V.; Szanyi, Janos; Rossi, Liane M.. Safety of Tris(dibenzylideneacetone)dipalladium(0) And the article was included in ChemCatChem in 2020. The article conveys some information:

Bimetallic Ni-Pd and monometallic reference catalysts were prepared by decomposing organometallic precursors, Ni(cod)2 and Pd2(dba)3, leading to nanoparticles with sizes ranging from 3-6 nm. Two different synthesis procedures were followed, solution synthesis using capping ligand (hexadecylamine) followed by impregnation of pre-formed nanoparticles on SiO2, called Sol-immobilization (SI) and direct precursor decomposition onto SiO2, without stabilizer, called direct decomposition (DD). Samples prepared by SI procedure are alloyed bimetallic nanoparticles, whereas samples obtained by DD one show phase segregation. Interestingly, DD samples show better activity for CO2 hydrogenation into CO (reverse water-gas shift reaction – RWGS) than SI ones. The best compromise between activity for CO2 activation (at lower temperature) and CO selectivity was achieved with Ni DD and NiPd DD catalysts. Moreover, the addition of palladium increased the concentration of surface undercoordinated sites, which chemisorb CO weakly, thus improving activity and selectivity, in opposition to other samples that chemisorb CO strongly, in multibond configuration. In the presence of Pd, different decomposition rates drives the formation of smaller and more active Ni clusters. The knowledge acquired here on the effect of synthesis conditions on the catalytic properties of Ni-Pd catalysts should guide us to better catalysts for CO2 transformations into valuable products. The results came from multiple reactions, including the reaction of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Safety of Tris(dibenzylideneacetone)dipalladium(0))

And the article was published in Scientific Reports in 2019. Quality Control of Tris(dibenzylideneacetone)dipalladium(0) The author mentioned the following in the article:

IGF1R and CD44 are overexpressed in most advanced melanomas so we designed chemotherapeutic nanoparticles to target those receptors. Tris(dibenzylideneacetone)dipalladium (Tris DBA-Pd) is a novel inhibitor of N-myristoyltransferase 1 (NMT-1) and has proven in vivo activity against melanoma. However, poor solubility impairs its effectiveness. To improve its therapeutic efficacy and overcome drug resistance in advanced melanomas, we synthesized Tris DBA-Pd hyaluronic acid nanoparticles (Tris DBA-Pd HANP) and evaluated them against in vivo xenografts of LM36R, an aggressive BRAF mutant human melanoma resistant to BRAF inhibitors. We treated xenografted mice in four arms: empty HANPs, free Tris DBA-Pd, Tris DBA-Pd HANPs, and Tris DBA-Pd HANPs with IGF1R antibody. The Tris DBA-Pd HANP group was the most responsive to treatment and showed the greatest depletion of CD44-pos. cells on IHC. Surprisingly, the HANP containing IGF1R antibody was less effective than particles without antibody, possibly due to steric hindrance of IGF1R and CD44 binding. Tris DBA-Pd nanoparticles are an effective therapy for CD44-pos. tumors like melanoma, and further development of these nanoparticles should be pursued.
