Nickel complexes having a bulky tri(sec-alkyl)phosphine ligand catalyze hydroheteroarylation of alkynes at 35 degrees C. Selective activation of an Ar-H bond over an Ar-CN bond of N-protected 3-cyanoindoles is achieved by a proper choice of ligand an

The oxidative addition of H2 to the iridium(I) chelates IrX(CO) (dppe) (X(-) = Cl(-), Br(-), I(-), Cn(-), H(-), PPh3; dppe = 1, 2-bis-(diphenylphosphino)ethane) proceeds with > 99% steroselectivity to yield a cis dihydride product with one hydride tr
