Alkyl halides were treated with protonated heteroaromatic bases in the presence of 1,1,1,3,3,3-hexamethyl-2,2-bis(trimethylsilyl)trisilane under photochemical conditions to give the corresponding alkylated heteroaromatic bases easily. The alkylation of protonated heteroaromatic bases with 1,1,1,3,3,3-hexamethyl-2-(trimethylsilyl)trisilane proceeded effectively under photochemical conditions or thermal conditions. The present method is the first report on the alkylation of heteroaromatic bases under non-oxidative conditions.
在1,1,1,3,3,3-六甲基-2,2-双(三甲基甲硅烷基)三硅烷存在下,在光化学条件下用质子化杂芳族碱处理烷基卤,很容易得到相应的烷基化杂芳族碱。质子化杂芳族碱基与1,1,1,3,3,3-六甲基-2-(三甲基甲硅烷基)三硅烷的烷基化在光化学条件或热条件下有效进行。本方法是第一个关于非氧化条件下杂芳族碱基烷基化的报道。
