An eco-friendly and efficient method for the synthesis of organophosphinates via an electrochemical cross-dehydrogenative-coupling reaction between alcohols and secondary phosphine oxides has been developed. This electrochemical reaction was conducted at room temperature without the addition of any oxidant, metal catalyst, or additive, which provides a new strategy for the synthesis of organophosphinates

reagents with stable and readily available ammonium carbonate as an ammonia source is disclosed herein for the first time. This ethyl bromoacetate-mediated primary amination proceeds smoothly undermild and simple conditions, without any metal catalyst or oxidant. Moreover, this method is also appropriate for the reaction of Ar2P(O)–H with a variety of amines, alcohols, and phenols to construct P–N or P–O
本文首次公开了一种简便有效的方法,用于从 Ar 2 P(O)-H 试剂与稳定且易于获得的碳酸铵作为氨源合成伯膦酰胺。这种溴乙酸乙酯介导的伯胺化在温和简单的条件下顺利进行,无需任何金属催化剂或氧化剂。此外,该方法还适用于Ar 2 P(O)-H与多种胺类、醇类和酚类反应构建P-N或P-O键,操作方便,官能团耐受性好。 ,和广泛的底物范围。
