Irradiation of phenylacetonitrile and its derivatives (1) in the presence of triethylamine gave α-benzylated triethylamine (2), bibenzyl (3), and toluene (4) derivatives. The formation of these products was explained in terms of a benzylic radical intermediate formed by electron transfer between the substrate and triethylamine, followed by elimination of a cyanide anion from the radical anion of 1.
在三乙胺存在下,对苯乙腈及其衍生物(1)的照射生成了α-苄基三乙胺(2)、双苄基(3)和甲苯(4)衍生物。这些产物的形成可以用一种苄基自由基中间体来解释,该中间体是由底物与三乙胺之间的电子转移形成的,随后从1的自由基阴离子中消除一个氰离子。
