摘要：

分别以2,4,5-三氯苯胺和盐酸氨基脲、甲酸为起始原料, 设计并合成两个系列新型1,2,4-三唑啉酮类化合物(5, 7). 通过 1H NMR, MS和元素分析确证了其结构, 生物活性测定结果表明, 化合物5系列的除草效果优良, 而化合物7系列则基本没有除草活性, 但表现出很强的促进黄瓜子叶生根活性.

Abstract:

Triazolinone herbicides which is environment-benign have a broaden application perspective. Several triazolinone compounds such as amicarbazone, sulfentrazone, azafenidin and carfentrazone-ethyl have been developed as herbicides. In order to search for novel 1,2,4-triazolinone derivatives with high herbicidal activities, 2-(2,4,5-trichlorophenyl)-4-(2-substituted-benzyl)-5-methyl-2H-1,2,4-triazol-3(4H)-ones and 2,4-disubstitued-1,2,4-triazol-3(2H)-ones were designed and synthesized. Their structures were identified by 1H NMR, MS and elemental analysis. The results of preliminary biological activity tests show that some compounds display excellent herbicidal activity and some display good activity of promoting cucumber cotyledon root-formation at 1.5 kg/ha.

Key words: 1,2,4-Triazolinone; Herbicidal activity; Cucumber cotyledon root
