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
在氧气氛下,通过氧杂钒(V)化合物氧化苄基硅烷和苄基锡化合物,得到相应的芳族醛(酮)和/或羧酸。在苄基锡的反应中,氧钒(V)化合物可以减少至0.5摩尔量。苄基硅烷的反应被认为是通过电子转移过程进行的。另一方面,苄基锡可能会发生金属转移反应以生成苄基钒物种,它们会通过非自由基过程直接转移到羰基化合物上。
