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 under mild 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。
