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
