describes a three-component, Ni-catalyzed reductive coupling that enables the convergent synthesis of tertiary benzhydryl amines, which are challenging to access by traditional reductive amination methodologies. The reaction makes use of iminium ions generated in situ from the condensation of secondary N-trimethylsilyl amines with benzaldehydes, and these species undergo reaction with several distinct classes

The invention of a well-defined Cu(III) fluoride complex Me4N+[Cu(CF3)3(F)]- 1 enabled to access a versatile of functionalized Cu(III) complexes [Me4N]+[Cu(X)(CF3)3]- (X = C6F5, C6F5C≡C, CN, Cl, N3, tBuOO, SCN, OAc, SAr), many of them for the first time. The availability of these complexes allowed us to evaluate the trans-influence order of ligand in Cu(III) complexes: Bn > CF3– > C6F5– > N3– > py
