In the presence of SnCl4·5H2O and acetic acid, a mixture of trimethylsilyl azide and tetraallyltin underwent 1,4- and subsequently 1,2-addition, respectively, with the α,β-unsaturated aldimines to give 1,3-hydroxy azides in good yields, where the hydrolysis of the intermediary imino species was found to be crucial.
在SnCl4·5H2O和醋酸的存在下,三甲基硅烷叠氮化物和四烯基锡的混合物与α,β-不饱和醛亚胺分别发生了1,4-和随后1,2-加成,生成了产率良好的1,3-羟基叠氮化物,其中中间亚胺物种的水解被发现是关键步骤。
