The application of air stable preformed [(R)-BINAP]PdBr2, [(S)-BINAP]PdBr2, [(R)-Tol-BINAP]PdBr2, and [(S,S)-CHIRAPHOS]PdBr2 complexes in the one-pot asymmetric reductive amination of various carbonyl compounds, leading to chiral amines in very good yields with high enantioselectivities (<99% ee), is reported.

dual-catalytic strategy for the radical decarboxylation functionalization of aliphatic carboxylic acids. The photoinduced ligand-to-iron charge transfer process under light was initially occurred to generate an unstabilized alkyl radical, and the copper catalyst delivered the radical and enabled the subsequent coupling reactions to form C–N or C–C bonds. By merging iron-catalyzed decarboxylation with copper catalysis
