Abstract:
2-Mercapto-5,6-difluorobenzimidazole reacts with aliphatic and alicyclic ketones in acetic acid in the presence of catalytic amount of sulfuric acid to afford fluorinated derivatives of 2,3-disubstituted benz{[}4,5]imidazo{[}2,1-b]{[}1,3]thiazoles. Reaction with aromatic alpha -haloketones Occurs in another way: to furnish 2-phenylacylthio-5,6-difluorobenzimidazoles that in the system acetic anhydride-pyridine undergo cyclization into the corresponding fluorinated derivatives of benz{[}4,5]imidazo{[}2,1-b]{[}1,3]thiazoles.
