Insertions into CH or CC bonds and addition reactions with CO or CS 2 confirm the formation of nitrenenickel(II) complexes as intermediates in the photolysis of diazido(phosphane)nickel(II) complexes. Without reactive substrates the nitrene intermediates decay to coordinatively unsaturated phosphane–nickel(0) complexes, which may initiate the photocatalytic cyclization of alkynes to the corresponding benzene derivatives.= bis(phosphane) ligand or (PEt 3 ) 2 .
