A convenient new synthetic approach to 3-aryl-1,2,4-triazoles has been developed. Chloralamides were obtained by high yield reactions between benzamides and chloral hydrate. These reacted with a phosphoruspentachloride/phosphorus oxychloride mixture undergoing a near quantitative conversion to N-(1,2,2,2-tetrachloroethyl)benzimidoyl chlorides, which were treated with hydrazine hydrate to directly

3-Diazo-3-1,2,4-triazoles convert to singlet 3-1,2,4-triazol-3-ylidenes which (1) effect directed electrophilic substitutions of benzenes and (2) coordinate with benzenoid substituents and nitro compounds to give decomposition or rearrangement products.
