The reactions of some phosphorus(III) halides with halogens in the strongly acidic solvents 25 oleum, HSFO3, and 100% H2SO4 have been investigated by means of 31P n.m.r. spectroscopy. The compound PCl3 and Br2, and PBr3and Cl2, react to give complex mixtures of products containing tetrahalogenophosphonium ions [PBr4–nCln]+, together with solvolysed species [PBr3–nCln(OH)]+(25 oleum) or PF3O(HSFO3)
已通过31 P nmr光谱研究了一些磷(III)卤化物与卤素在强酸性溶剂25发烟硫酸,HSFO 3和100%H 2 SO 4中的反应。化合物PCl 3和Br 2以及PBr 3和Cl 2反应生成复杂的混合物,该混合物包含四卤代phosph离子[PBr 4– n Cl n ] +和溶剂分解的物质[PBr 3– n Cl n(OH)]。+(25发烟硫酸)或PF 3 O(HSFO3)。尽管已从中鉴定出部分溶剂化的物质[ Pn n X 3– n(OH)] +(X = Cl或Br),但没有发现源自PI 3的卤代磷离子[PX n Y 4– n ] +的证据。解决方案。
