摘要：

Benzylsilane and benzyltin compounds were oxidized by oxovanadium(V) compound under an oxygen atmosphere to afford the corresponding aromatic aldehydes (ketones) and/or carboxylic acids. In the reaction of benzyltins, oxovanadium(V) compound can be reduced to 0.5 molar amounts. The reaction of benzylsilanes is considered to proceed via electron-transfer process. On the other hand, benzyltins may undergo transmetallation to generate benzylvanadium species, which are directly transferred to the carbonyl compounds via non-radical process.
