Department of Chemistry, University of Gorakhpur, Gorakhpur (U. P.) Manuscript received 21 September 1978, revised 29 January 1979. accepted 27 April 1979 Seven 5-aryl/aryloxymethyl-1,3,4-oxadiazol-2-thiones, three 3-hydroxymethy1-5-aryl/ aryloxymethy1-1,3,4-ozadiazol-2-thiones, forty 3-arylaminomethyl/ethylideno/benzyl­ideno-aryl/aryloxymethyl-1,3,4-oxadiazol-2-thiones and thirty N,N'-bis-(3-methylene/ ethylideno /benzylideno-5-aryl /aryloxymethyl-1,3,4-oxadiazol-2-thione)-benzidines/\(p\)-phe­nylene diamines have been synthesised with a view to study their antifungal activity. Most of these compounds have been screened for their antifungal activity against A. \(niger\) and A. \(flavus\) and found to be antifungal
