An iridiumcatalyst enables the reductive amination of carbonylgroups with unprecedented substrate scope, selectivity, and activity using formic acid as the hydrogen source (see scheme). The catalyst system provides significant improvement over commonly used boron hydrides.

The dinuclear Rh(III) species [Cp*RhCl2]2 catalyzes the hydroamination reaction between an aromatic terminalalkyne (ArCCH) and an aniline (Ar′NH2), in the presence of a salt additive, to afford the ketimine Ar′N═C(Me)(Ar). A reaction pathway has been proposed on the basis of experimental and computational studies.
