摘要

Abstract α, α??Dibromoketones (2) have been found to be a superior alternative to the conventionally used α??bromoketones (1) for performing the Hantzsch thiazole synthesis. 1 These crystalline, nonlachrymatory compounds are more reactive than 1 as demonstrated by their reaction with 3, 5??dimethyl??1??thiocarboxamide (5).
