Synthesis, Crystal Structure and Biological activity of N-(5-(o-tolyl)-1, 3, 4-thiadiazol-2-yl)cyclopropanecarboxamide

Abstract

A new 1, 3, 4-thiadiazole compound, N-(5-(o-tolyl)-1,3,4-thiadiazol-2-yl) cyclopropanecarboxamide, was synthesized and its structure was confirmed by 1H NMR, MS and HRMS. The single crystal structure of the title compound was determined by X-ray diffraction. The preliminary biological test showed that the synthesized compound has moderate herbicidal activity against Brassica campestris and fungicidal activities against Sclerotinia sclerotiorum(Lib.) de Bary, Rhizoctonia solanii, Fusarium oxysporum, Corynespora cassiicola, and Botrytis cinerea.
