Abstract : The trimethylsilyl-, trimethylgermyl-, and trimethyl- stannylbenzene tricarbonyl derivatives of Cr were prepared by the reaction of the trimethylphenyl compounds of Si, Ge and Sn with chromium hexacarbonyl. The possibility of carrying out a transmetalation reaction between trimethylstannylbenzene chromium tricarbonyl and phenyllithium in ether at low temperature was investigated since selective attack by the Li reagent at the Sn-phenyl linkage could give a Cr carbonyl complex of phenyllithium. Carbonation of the reaction mixture, however, gave no benzoic acid chromium tricarbonyl, and it is thus likely that attack of phenyllithium occurred at the carbonyl groups rather than at the Sn-C bond.
