The addition of a range of amines to vinyldiphenylphosphine oxide was examined under different reaction conditions. The methodology provides mixed phosphorus-nitrogen donor ligands R-NH(CH2CH2PPh2) 3 and R-N(CH2CH2PPh2)2 4, which could be prepared in high yields and purity in two simple steps. Labelling study revealed a non-concerted mechanism and the X-ray crystal structure of 1e is reported.
在不同反应条件下,研究了将一系列胺加成到乙烯基二苯基氧化膦的方法。该方法提供了混合磷氮供体型配体R-NH(CH2CH2PPh2)3和R-N(CH2CH2PPh2)2,这些配体可通过两个简单步骤以高产率和高纯度制备。标记研究表明存在非协同机理,并报道了1e的X射线晶体结构。
