refluxed in CHCl3. The (alkyl)bis(alkynyl)iridium(III) compound Ir(CH3)(C⋮C(p-C6H4CH3))2(CO)(PPh3)2 (4) reacts with aqueous HCl to give H2CCCH(p-C6H4CH3) (9). Complex 3 reacts with excess DCl to give the d5 isotopomer CD3CDCD(p-C6H4CH3) (7-d5), while the reaction of 4 with DCl gives the d1 isotopomer H2CCCD(p-C6H4CH3) (9-d1). Plausible reaction pathways are discussed for the formation of 7 and 9 and for
