Abstract: The comparative study on kinetics and mechanism was made to examine further the importance of CO bridging concept to the reactivity of metal clusters in the CO substitution by L of M4(CO)12-nLn(M=Co, Ir; L=phosphorous ligand; n=1,2) in the presence of Me3NO. Thesecond-order rate law and kinetic behavior arc the same as that reported earlier on such reaction and hence provide a common basis for comparision. The reaction rates of Ir compoundsare greater than those of corresponding Co compounds (Co3(CO)11L and theM3(CO)12 on studies earlier from different are here obtained results The paper. this in ligandsstudied phosphorous with Fe > Ru > Os and this was discussed in terms of the presumed important contributionof CO bridging to the rates of associative reactions in metal carbonyl clusters. Some other effects of structural factors on rates of the oxygen atom transfer to metal carbonyls were also discussed.
