Abstract

1-Phenyl-1,2,4-triazole is lithiated exclusively at the C-5 position. 5-Methyl-1-phenyl-1,2,4-triazole produces the 5-lithiomethyl derivative; while the 5-ethyl, 5-methoxymethyl, and 5-acetic acid derivatives af 1-phenyl-1,2,4-triazole undergo exclusive lithiation of the C-5-methylene group. 5-Thiomethyl-1-phenyl-1,2,4-triazole is lithiated on the C-5 thiomethyl group.
