experimental part, p. 561 - 569 (2010/05/18)
A series of new heterocyclic β-ketosulfides was prepared by the reaction of the corresponding heterocyclic thiols with α-bromoacetophenone and its derivatives. Oxidation of the products using m-CPBA gave the corresponding heterocyclic β-ketosulfones, whic

2-Mercaptobenzimidazole (1) reacts with aromatic ketones 2a-d in acidified acetic acid giving 2-benzimidazolylthioacetophenones 3a-d, which on cyclization yield thiazolo[3,2-a]-benzimidazoles 4a-d. Acetylation of 3a,d gave the N-acetyl derivatives 5a,d. C
