The compound Ru(CO)2(triphos) (triphos = MeC(CH2PPh2)3) reacts with a number of acid chlorides RR′CHCOCl to form [RuH(CO)2(triphos)]Cl and the corresponding substituted ketenes RR′CCO. A quantitative study of the reaction of Ph2CHCOCl shows that Ph2CCO is formed in a 1 : 1 stoichiometry. The compound Ru(CO)3(PPh3)2 also reacts with Ph2CHCOCl, forming Ph2CCO and the unstable hydride [RuH(CO)3(PPh3)2]Cl
