  A reinvestigation of the reaction of Ir(CO)Cl(PPh3)2, 1 with   HSnPh3 has revealed that the oxidative-addition product   Ir(CO)Cl(PPh3)2(H)(SnPh3), 2 has the H and SnPh3 ligands in   cis-related coordination sites. Compound 2 reacts with a second   equivalent of HSnPh3 by a Cl for H ligand exchange to yield the   new compound H2Ir(CO)(SnPh3)(PPh3)2, 3. Compound 3 contains two   cis- related hydride ligands. Under an atmosphere of CO, 1 reacts   with HSnPh3 to replace the Cl ligand with SnPh3¬ and one of the   PPh3 ligands with a CO ligand and also adds a second equivalent   of CO to yield the 5-coordinate complex Ir(CO)3(SnPh3)(PPh3), 4.   Compound 4 reacts with HSnPh3 by loss of CO and oxidative   addition of the Sn-H bond to yield the 6-coordinate complex   HIr(CO)2(SnPh3)2(PPh3), 5 that contains two trans-positioned   SnPh3 ligands.
