Ten 2-aryl, 7-alkyl/aryl-5-hydro 1,3,4-thiadiazolo [3,2-a], [1,3,5]-triazine (IIIa-j), 2-aryl, 7-alkyl/aryl 1,3,4-thiadiazolo [3,2-a] [1,3,5]-triazine 5-ones (IVa-j) and their thiones (Va-j) each, have been synthesized by chemoselective cyclization of corresponding 2-amidino-5-aryl 1,3,4- thiadiazole (IIa-j) with HCHO/Toluene, ClCOOEt. and CS2/KOH respectively. The required amidines (IIa-j) were prepared by reacting 2- amino, 5-aryl 1,3,4-thiadiazole (Ia-e) either by reaction of alkyl cynide or aryl cynide (R-CN). Above compounds were evaluated for fungitoxicity against two fungal species, viz. Alternaria solanai and Puccinia graminia tritici and the screening results correlated with structural features of the tested compounds.
