Selective pyrolytic deprotection of 2-ethyl and 2-cyanoethyl-4-arylidenimino-1,2,4-triazol-3(2H)-ones and their 3(2H)-thiones was studied by flash vacuum pyrolysis. This study is useful in regioselective synthesis of 2-and 4-substituted 1,2,4-triazoles of potential biological applications. The kinetic results and product analysis lend support to a reaction pathway involving a six-membered transition state.
