Synthesis and acaricidal activity of 3-aryl-5-arylmethyl-1,3,4-oxa diazol-2 -ones


, : Synthesis and acaricidal activity of 3-aryl-5-arylmethyl-1,3,4-oxa diazol-2 -ones. Pesticide Science 40(2): 141-146

A series of new 1,3,4-oxa(thia)diazol-2(3H)-ones were synthesized and tested as acaricides. High activities against eggs of Tetranychus urticae (Koch) were found for derivatives bearing an ortho-halo-substituted phenyl group in position 3, and a benzyl group para-substituted by a branched C-3-C-6, alkoxy group in position 5 of the hetero-ring. The best compounds attained the miticidal potency of clofentezine.
