Benzimidazol-2-ylalkyl N-aryl(or cyclohexyl)dithiocarbamates (IIIa-f) have been submitted to the oxidative and chemoselective cyclization with I2 and SOCl2 to yield 2-aryl(or cyclohexyl)imino-4-methyl(or unsubstituted)-(4H)-1,3,4-dithiazino benzimidazoles (IVa-f) and 1-aryl (or cyclohexyl)-4-methyl (or unsubstituted)-(4H)-1,3,4-thiadiazino benzimidazole-2-thiones (Va-f), respectively.The -2-thiones (V) have been oxidized with HgO to their -2-one analogues (VI).Compounds IVb, IVc and Vc have displayed the in vitro fungitoxicity against A, niger and F. oxysporium (at 1000 ppm concentration), being comparable to that of a commercial fungicide, mancozeb.
