The irradiation of a nitrogen-flushed acetonitrile suspension of titanium dioxide in the presence of benzyltrimethylsilane, its 4-methoxy derivative or 4-methoxyphenylacetic acid as the donors and maleic acid, maleic anhydride or related nitriles as the acceptors leads to the corresponding benzylsuccinic acid derivatives via electron, hole transfer and fragmentation of the benzyl radical cation (such
在苄基三甲基硅烷,其4-甲氧基衍生物或4-甲氧基苯基乙酸为施主,马来酸,马来酸酐或相关的腈为受主的存在下,辐照二氧化钛的氮吹扫乙腈悬浮液会生成相应的苄基琥珀酸衍生物经由电子,空穴转移和苄基阳离子的断裂(这种断裂对于4-甲氧基甲苯来说太慢了)。给出了反应的原理并评价了该方法的综合意义。
