the corresponding 2,4-dichloro-1,3,2,4-diazadiphosphetidine 2,4-dioxides, which are readily converted into the 2,4-bisdimethylamino- or 2,4-bisthiomethyl derivatives. The n.m.r. spectra of these compounds are discussed in the light of dπ–pπ bonding, and virtual coupling.
NN' -二烷基或-diaryl-2,2,2,4,4,4六氯1,3,2,4- diazadiphosphetidines用液体二氧化硫反应,以提供到相应的2,4-二氯一个方便的途径-1,3,2,4-二氮杂二磷酸环丁酯2,4-二氧化物易于转化为2,4-双二甲基氨基-或2,4-双硫代甲基衍生物。这些化合物的核磁共振谱中的光中讨论d π - p π键合,和虚拟耦合。
