Based on data for the acidity relationship of phosphines and phosphinous acids and water in dimethyl sulfoxide and water, a simple method is reported for the generation of phosphide and phosphinite anions by the action of concentrated aqueous alkali on primary and secondary phosphines as well as phosphinous acids in dimethyl sulfoxide or other dipolar aprotic solvents. Alkylation of the anion yields secondary and tertiary phosphines, polyphosphines, functionally substituted phosphines as well as similarly substituted phosphine oxides. Phosphinous acids have been alkylated in various solvents in two-phase systems containing concentrated aqueous alkali and tetrabutylammonium iodide as phase transfer catalyst.
基于二甲基亚砜和水中的膦和亚膦酸与水的酸度关系数据,报道了一种简单的方法,通过浓碱水溶液作用于二甲基亚砜或其他偶极非质子溶剂中的伯膦、仲膦及亚膦酸,生成膦化物和亚膦酸根阴离子。通过烷基化反应,这些阴离子可转化为仲膦、叔膦、多膦、功能化取代膦及其类似取代的膦氧化物。在含有浓碱和四丁基碘化铵作为相转移催化剂的两相体系中,亚膦酸已在多种溶剂中进行烷基化。
