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
