It has been found from 1Н NMR data that bromination of S-allyl derivatives of 3-mercapto-1,2,4-triazoles proceeds to give the bromocyclization products ([1,3]thiazolo[3,2-b][1,2,4]triazolium and [1,2,4]triazolo[3,4-b][1,3]thiazinium bromides) and the products of bromine addition to the double bond of alkenyl moiety.По данным ЯМР 1Н установлено, что бромирование S-аллильных производных 3-меркапто-1,2,4-триазолов сопровождается образованием продуктов бромциклизации (бромиды [1,3]тиазоло[3,2-b][1,2,4]триазолия и [1,2,4]триазоло[3,4-b][1,3]тиазиния) и продуктов присоединения брома по двойной связи аллильного фрагмента
