functioned as a single catalyst for two successive steps in a one-pot procedure. First, the hydroamination of alkynes with anilines took place to give the Markovnikov product. Then, hydrosilylation of the imine intermediates by treatment with a hydrosilane substrate afforded the corresponding secondary amines.

The in situ generated nickel hydride complex, [Ni(Mes2NHC)HCp], and its cationic analogue, [Ni(Mes2NHC)(NCMe)Cp](PF6), are efficient and chemoselective pre-catalysts for the hydrosilylation of both aldimines and ketimines under mild conditions.

Inspired by Nature: A conceptually new design for a catalyst, combining a metal center abutted to an organic hydride donor, is demonstrated for the formate‐driven transfer hydrogenation of imines under ambient conditions. A key step, transfer of hydride from the organohydride donor to the metal‐polarized substrate, mirrors that in metallo‐(de)hydrogenase enzymes.

of the type [Cp*M(LBI)Cl][PF6]2 (M=Rh, Ir) have been made and fully characterised by cyclic voltammetry, UV/Vis spectroelectrochemistry, and, for the IrIII congener, X‐ray crystallography. [Cp*Rh(LBI)Cl][PF6]2 catalyses the transferhydrogenation of imines by formate ion in very goods yield under conditions where the corresponding [Cp*Ir(LBI)Cl][PF6] and [Cp*M(phen)Cl][PF6] (M=Rh, Ir) complexes are
