Palladium nanoparticles (NPs) stabilized by a zwitterionic surfactant are revealed here to be good catalysts for the reductive amination of benzaldehydes using formate salts as hydrogen donors in aqueous isopropanol. In terms of environmental impact and e

We describe the first thiourea-catalyzed C?F bond activation. The use of a thiourea catalyst and Ti(OiPr)4 as a fluoride scavenger allows the amination of benzylic fluorides to proceed in moderate to excellent yields. Preliminary results with S- and O-based nucleophiles are also presented. DFT calculations reveal the importance of hydrogen bonds between the catalyst and the fluorine atom of the substrate to lower the activation energy during the transition state.

The halide complexes TpRhCl2(MeOH) and TpMe2RhI2(CO) (Tp = hydrotris-(pyrazolyl)borate; TpMe2 = hydrotris-(3,5-dimethylpyrazolyl)borate) were synthesized by reactions of RhCl3 with K[Tp] in methanol and TpMe2Rh(CO)2 with iodine, respectively. Reactions of TpMe2RhCl2(MeOH) and TpMe2RhI2(CO) with 1,10-phenanthroline afford the phenanthroline derivatives [TpMe2Rh(phen)X]+ (X = Cl, I). The structures of TpRhCl2(MeOH) and TpRhI2(CO) were determined by X-ray diffraction. Tris(pyrazolyl)borate rhodium complexes effectively catalyze the reductive amination and the reductive esterification of aldehydes in the presence of carbon monoxide.
