Herein, a new solvent-free synthetic method using P(O)-OH compound and alkyl chloride for phosphinate compounds is disclosed. This transformation proceeds smoothly under the promotion of a lone base and presents the advantages of an easily available raw material source, a simple post treatment process, good functional group tolerance and high reaction efficiency. Good yield was obtained when the reaction
在此,公开了一种使用P(O)-OH化合物和烷基氯制备次膦酸盐化合物的无溶剂合成新方法。这种转化在孤碱的推动下顺利进行,具有原料来源易得、后处理工艺简单、官能团耐受性好、反应效率高等优点。当反应放大至克级时,收率良好,P(O)-OH化合物与烷基氯化物的摩尔比可降至1:2。该协议为制备磷衍生物提供了一种实用的方法。此外,通过31 P NMR探索了反应机理。

in its activity with acetylsalicylic acid. In contrast to the latter acid, this oxide produces no ulcerogenic effect even at a dose of 1/3 LD50. Therefore, it was of interest to continue the search for new antiinflammatory and analgesic agents in the series of phosphoryl-containing compounds. The purpose of this work was to study the antiinflammatory and analgesic properties and the acute toxicity of

A copper-catalyzedoxidative cross-dehydrogenative coupling (CDC) strategy of secondary phosphine oxides and alcohols for the synthesis of various phosphinate esters was proposed. Under the mild reaction conditions (CuCl2·2H2O/K2S2O8, at room temperature for 3–12 h under air), a variety of substrates were well-tolerated and afforded the desirable compounds in moderate to excellent yields.
