Synthesis of 2-Aryl Amino-5-Aryl/Aryloxy Methyl-1,3,4- Oxadiazles, 2-Aryl Amino-5-Aryl/Aryloxy Methyl-1,3,4- Thiadiazoles, N1-Aryl/Aryloxy Acetyl-3,5-Dimethyl Pyrazoles and N1-Aryl/Aryloxy Acetyl-3-Methy1-5- Pyrazolones as Possible Fungicides

Chemistry Department, University of Gorakhpur, Gorakhpur (U. P.) Manuscript received 29 July 1978, revised 24 November 1978, accepted 22 February 1979 Six 2-arylamino-5-aryl/aryloxy methyl-1,3,4,-oxadiazoles, eight 2-aryl amino-5-aryl/ aryloxy methyl-1,3,4,-thiadiazoles, three N1-aryl/aryloxy acetyl-3,5-dimethyl pyrazoles and three N1- aryl/ aryloxy acetyl-3-methyl-5-pyrazolones have been synthesised with a view to study their antifungal activity. All the compounds have been screened for their antifungal activity against 'A.\(flavus\)' and 'A. \(niger\)' and found to be antifungal
