Osmium hydrido alkyl carbonyl complexes cis-Os(CO)4(H)R (R = Me, Et) can be prepared by alkylation of [Os(CO)4H]- with the corresponding alkyl fluorosulfates. The thermal decomposition of these complexes gives dinuclear and trinuclear derivatives HOs2(CO)8R and ROs3(CO)12R. Other dinuclear complexes can be obtained from similar reactions of hydrides with alkyl carbonyl complexes. The course of the reaction of cis-Os(CO)4(H)CH3 with Ph3P depends upon the reaction conditions: with complete exclusion of air (Ph3P)Os(CO)4 and CH4 are obtained, whereas small amounts of air induce the rapid operation of a radical-chain substitution mechanism and the formation of Os(CO)3(PPh3)(H)CH3.
