Benzoyltrimethylsilanes are prepared in moderate to good yields (24-81%) from the novel reaction of hexamethyldisilane with benzoyl chlorides, catalyzed by dichloro(η3-allyl)dipalladium(II) (1) and triethyl phosphite. The reaction tolerates a wide variety of meta and para substituents on the phenyl ring. Hexamethyldigermane and several bimetallic silicon-germaniums were also used in the reaction; the relative rates of group transfer from competitive benzoylation reactions are PhMe2Ge > Me3Ge > PhMe2Si > Me3Si. Ortho-substituted benzoyl chlorides and aliphatic acid chlorides gave lower yields of the corresponding acyltrimethylsilanes under the same reaction conditions.
