摘要: 利用P(Net2)3与双官能基底物的环缩合反应合成了一系列新型五元磷杂环化合物.化合物的结构经1HNMR,31PNMR,MS和元素分析等手段证实.对化合物l作了X射线单晶衍射,确定五元磷杂环为平面结构及P_N键具有dπ-pπ性质.初步生物活性测定表明部分化合物具有较好的选择性除草活性.

Abstract: In order to look for a new herbicide, a series of novel phosphorus heterocyclic compounds have been prepared by the reaction of P(NEt2)3 with compounds containing 1,2 diamino groups at a high temperature. The structures of compounds Ⅱ were characterized by 1H NMR and elemental analysis, some of which were characterized by 31P NMR and MS. The compound Ⅱl was analyzed by X-ray diffraction. The coplanar heterocycle and dπ-pπ electronic phenomenon of P_N bond were found. The preliminary biological tests indicated that some of them showed a better selective herbicidal activity.

Key words: Cyclocondensation, Five membered phosphorusheterocycle, X-ray diffraction, Herbicidal activity
