Synthesis of Some Bis-(oxadiazolyl) sulphides, Sulphones and 2-Substituted-[1, 3, 4]-oxadiazolo-[2, 3, b] quinazol-5-ones as Potential Fungicides

Abstract

Several bis-(5-substituted-1, 3, 4-oxadiazol-2-yl) sulphides and sulphones derived from 2-mercapto-5-aryl/aryloxymethyI-1, 3, 4-oxadiazoles have been prepared. The mercapto oxadiazoles have also been condensed with anthranilic acid to give 2-substituted-[1, 3, 4]-oxadiazolo-[2, 3, b] quinazol-5-ones. Some of these compounds have been tested against two species of fungi.
