Received Date: 27 March 2001

Fund Project: The project was supported by the NNSF of China (Grant No. 29802002), the NSF of Hubei Province, the Dawn Plan of Science and Technology for Young Scientists of Wuhan City and Foundation for University Key Teacher by the Ministry of Education of China.

A series of diheterocyclic compounds containing 1,2,4-triazolo [l,5-a]pyrimidine and 1,3,4-oxadiazole were designed and synthesized starting from 2-mercapto-5,7-dimethyl-l,2,4-triazolo [ 1,5-a] pyrimidine. The structure of all compounds prepared were confirmed by H NMR spectroscopy and elemental analysis. The preliminary bioassay indicated that the title compounds displayed good fungicidal activity against Rhizoctonia solani.
