The phosphines PHRPh (R = H, Ph) have been introduced into MHCl(CO)(PPh3)3 to give MHCl(PHRPh)(CO)(PPh3)2 (M = Ru, Os). Hydride cleavage with HClO4 in MeCN gives [MCl(PHRPh)(CO)(MeCN)(PPh3)2]ClO4 and carbonylation of these salts produces [MCl(PHRPh)(CO)2(PPh3)2]ClO4. The reactions of M(CO)2(PPh3)3 with PHRPh indicate that a simple substitution of PPh3 is the predominant reaction and not oxidative addition of the P-H bond. In most cationic complexes of PHRPh rapid H/D exchange of the phosphorus-bound proton occurs in the presence of D2O.
