diorganodithiophosphinates and diphenylantimony(V) bromide oxide (SbPh2OBr)2, led to antimonyreduction while dithiophosphinate oxidation followed a complex path varying in detail with the nature of the organic groups on dithiophosphinate. Antimony(III) dithiophosphinates, SbPh2(S2PR2) where R Me, Et and Ph, have been isolated and characterised and an X-ray structure determination for the methyl derivative
三种二有机二硫代次膦酸酯与二苯基溴化锑(V)氧化物(SbPh 2 OBr)2之间的反应导致锑的还原,而二硫代次膦酸酯的氧化遵循一条复杂的路径,该路径随二硫代次膦酸酯上有机基团的性质而变化。二硫代亚膦酸锑(III)SbPh 2(S 2 PR 2)(其中RMe,Et和Ph已被分离并表征),X射线结构测定的甲基衍生物显示出处于固态的弱缔合二聚体,介于(SbPh 2 S 2 PPh 2)2和[Sb(4-MeC 6 H 4)2 S 2 PEt] 2。
