BROMINATION OF SUBSTITUTED 5H-IMIDAZO[1,2-<i>b</i>]-1,2,4-TRIAZEPIN-4-ONES AND -THIONES

Abstract

The reactions of substituted 5H-imidazo[1,2-b]-1,2,4-triazepin-4-ones and -thiones with bromine and N-bromosuccinimide have been studied. Derivatives of 3- and 8-bromo-, 3,8-dibromoimidazo[1,2-b]-1,2,4-triazepine and 5H-2-bromomethyl-3-methyl-7,8-diphenylimidazo[1,2-b]-1,2,4-triazepin-4-one are formed, depending on the degree of substitution, the nature of the brominating agent, and the reaction conditions.
