tris(dimethylamino)phosphine selenide, esters of selenophosphoric acid, and esters of selenophosphonic acid react with dihalogens and sulfurylchloride to form halogenoselenophosphonium salts (P–SeX)+X−. The latter undergo deselenization via ligand exchange to form phosphonium salts (P–X)+X− and elemental selenium. The stability of these salts depends on the substituents at the phosphorus atom and the type of counter
膦硒化物, 三(二甲氨基)膦硒化物, 酯类 的 硒磷酸, 和 酯类 的 硒代膦酸 与二卤素反应并 硫酰氯到形式halogenoselenophosphonium盐(P-性别)+ X - 。后者通过 配体交换形式鏻盐(P-X)+ X -和元素硒。这些盐的稳定性取决于磷原子上的取代基和抗衡离子的类型。salts盐可能与相应的equilibrium盐处于平衡状态磷烷,这证明了 酯类含有邻亚苯基配体。salts盐的结构,磷烷 和其他磷化合物的支持 31 P NMR光谱数据和电导率。其他证据来自卤代硒代phosph盐与环己烯。
