摘要: 利用P(NEt2)3与双酰胺类化合物在干馏条件下的环缩合反应合成了一系列含双芳氧乙酰基的新型五元磷杂环,对所合成的化合物进行了元素分析和谱学表征.初步生物活性测定表明,部分化合物具有优良的选择性除草活性.合成中首次发现此类磷杂环的P=Se与P—Se的转化现象,通过X射线单晶衍射确证了产物的结构,并发现产物分子间氢键的存在

Abstract: Aseries of new five membered phosphorus heterocycles were synthesized by cyclizing reaction of P(NEt-2)3 with substrates containing diamino groups.The products were characterized by elemental analysis and spectrascopy. The preliminary bioassays showed that some compounds possessed a good selective herbicidal activity. In addition for the first time, the rearrangement of P=Se to P-Se in such phosphorus heterocycle was found, and the structure of the product together with intermolecular hydrogen bonds was confirmed by X-ray diffraction.

Key words: Cyclizing reaction, Five-membered phosphorus heterocycle, Herbicidal activity, Rearran-gement of P=Se to P-Se, X-Ray diffraction
