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.
