Abstract
Photolysis in CH2Cl2 of the system 2[IrIIIHCl2(PPri 3)2]·H2(A), using light at 404 nm occurs with a quantum yield of 0.75 to give three new geometrical isomers of (A). N.m.r. spectroscopy and the chemical reactivity of the photoreaction mixtures have revealed the presence of equilibrium amounts of species containing molecular hydrogen. When (A) is irradiated in the presence of H2 the complex [IrVH3Cl2(PPri 3)2] is formed by an oxidative-addition reaction.Keywords
