On the basis of the 1,2,3,4-tetrahydrofluorenyl ligand, a simple approach was developed to new effective rhodium catalysts for the construction of C?C and C?N bonds. The halide compounds [(η5-tetrahydrofluorenyl)RhX2]2 (2

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.
Cobalt-Catalyzed Reductive Alkylation of Amines with Carboxylic Acids

Direct reductive alkylation of amines with carboxylic acid is carried out by using an inexpensive, air-stable cobalt/triphos catalytic system with molecular hydrogen as the reductant. This efficient synthetic method proceeds through reduction and condensation, followed by reduction of the in situ-generated imine into the amine in a green catalytic process.
