WebJan 1, 1974 · Further investigations of the reactions of IrH(CO)(PPh3)3 with activated, disubstituted acetylenes have now shown that several additional alkenyliridium complexes, in addition to the a-alkenyl-ir-acetylene compounds, are formed in these reactions, and that some of these are effective catalysts for the cyclotrimerization of disubstituted acetylenes. The earliest mention of IrCl(CO)(PPh3)2 is by Vaska and DiLuzio. The closely related IrBr(CO)(PPh3)2 was described in 1959 by Maria Angoletta, who prepared the complex by the treating IrBr(CO)2(p-toluidine) with PPh3 in acetone solution. In 1957, Linda Vallerino had reported RhCl(CO)(PPh3)2.
