| 摘 要： | A new type of diphosphorus heterocycles, 4,5- dioxo- 2- thio- 1,3, 2,4- diazadiphospholanes,has been synthesized by the condensation of carbamyl phosphoryl amidate and 4- substitutedphenyl phosphine dichloride, and then sulfurization. The cis- and trans-isomers of the com-pounds were separated by HPLC, and their structures were studied with ~1H NMR and ~(31)PNMR. It has been found that the cis- and trans-isomers have different chemical shifts (δ) anddifferent coupling constants. The preliminary bioassay shows that some of them possessstrong herbicidal activity.
