Abstract: Novel compounds, 2-arylamidothioacyl-3-isothiozolones 6 and 4-cyano5-methylthio-2-arylamidothioacyl-3-isothiozolones 7 were synthesized by reacting of 3-hydroxyisothiozoles(4, 5) with aryLIsothiocyanates 3 . The unique coupling constants of 4-H and 5-H of isothiazole ring of compounds 6 were discovered and explained according to the coplanarity of isothiazole ring with thioacyl group. The preliminary test of fungicidal activity showed that some of the title compounds possessed promising activity.

Key words: Isothiozole, Acyl thiourea, Synthesis, Fungicidal activity
