摘要: Abstract N-Phenacyl heterocyclic salts such as isoquinolinium, quinolinium, and pyridinium bromide react quickly with benzoyl isothiocyanate in the present of triethylamine to produce 1,4-diionic organosulfur derivatives. Cyclization dehydrogenation organosulfurs gave thiazoloisoquinolinium, or benzimidates. [Supplementary materials are available for this article.
