Di-[5,5-dimethyl-2-oxo-1,3,2-dioxaphosphorinan-2-yl] disulphide, obtainable from 2-methoxy-5,5-dimethyl-1,3,2-dioxaphosphorinan-2-thione and sulphurylchloride, or from 2-hydroxy-5,5-dimethyl-1,3,2-dioxaphosphorinan-2-thione or its salts with sulphur chloride, undergoes both desulphuration and deoxygenation on treatment with triphenylphosphine. The products of the reaction are triphenylphosphine oxide
二-[[5,5-二甲基-2-氧代-1,3,2-二氧杂膦酰基-2-基]二硫化物,可从2-甲氧基-5,5-二甲基-1,3,2-二氧杂磷酰氨基-2-硫酮获得磺酰氯,或2-羟基-5,5-二甲基-1,3,2-二氧杂膦酰-2-硫酮或其盐与氯化硫经三苯基膦处理后均进行脱硫和脱氧。该反应的产物是三苯基膦氧化物,三苯基膦硫化物,P -thiono- P '-oxodi- [5,5-二甲基-1,3,2-二氧磷杂-2-基]丙烷,和二- [5,5, -二甲基-2-硫醇-1,3,2-二氧杂磷(V)an-2-yl]氧化物。讨论了该反应的可能机理。
