Abstract

Bromination and iodination of 4-methallyl-5-methallylamino-1,2,4-triazole-3-thione lead to the annulation of five- and six-membered thiazaheterocycles, respectively. The usage of halogen excess does not give the product of 5-methallylamino group cyclization – the product of the bromine addition was isolated.
