Trimethylsilylation of 1,2,3-triazole regioselectively proceeded to give 2-trimethylsilyl-2H-1,2,3-triazole, which was treated with primary alkyl halides in the presence of tetrabutylammonium fluoride to give 1-alkyl-1H- 1,2,3-triazoles as a Sole product 1-Methyl-5-substituted 1H-1,2,3-triazoles were prepared by alkylation of 5-lithio-1-methyl-1H-1,2,3-triazole, and 1- methyl-4-substituted 1H-1,2,3-triazoles were obtained by alkylation of 4- lithio-1-methyl-5-phenylthio-1H-1,2,3-triazole followed by reductive desulfurization.
