nes were reacted with halomethylradicals generated by reaction of halo methanes with benzoyl peroxide or copper(I)chloride. In the former case the corresponding l-aryl-4-trihaloethyl-v-triazoles and 1-aryl-4-halomethyl-v-triazoles were formed. In the second case the corresponding l-aryl-4-trihaloethyl-5-morpholino v-triazoles accompanied by triazoles were obtained. Reaction mechanisms are discussed
