Oxidation of the decaruthenium carbonyl cluster [Z]2[Ru10C2(CO)24] (1) (Z+ = PPN+, Et4N+) with [Cp2Fe][BF4] (2 equiv) at room temperature in the presence of disubstituted alkynes forms the neutral derivatives Ru10C2(CO)23(C2RR′) (2, R, R′ = Ph2; 3, R, R′ = Tol2; 4, R, R′ = Ph, Me). Compounds 2-4 are readily reduced with methanolic hydroxide to produce the previously known [Ru10C2(CO)22(C2Ph 2)]2- (5) and its analogs.
