摘要: 2,4-Bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide1,commonly known as Lawesson's reagent (LR,1a),and Japanese Reagent (1b),are not only thiating agent for diverse carbonyl compounds1-3, but also they undergoes ring-closure reactions with contain substrates containing two functional groups to give phosphorus heterocycles which contain phosphonothioyliene {C6H4-P(S)〈} moiety. These heterocyclic compounds are of potential interest as herbicides,insecticides,and fungicides4,5. Glycinamides are known as biologically active materials, for example, herbicides, plant-growth regulator6. In order to look for potent herbicides7 and to extent the use of Japanese Reagent to other bifunctional substrates,its reactions with 3-alkyl-glycinamides 2 have been investigated and found to give new phosphorus heterocycles which possess Significant selective herbicidal activity against rape. Here are our results.
