compounds add readily to aldehydes, ketones, aldimines, and α,β‐unsaturated enones to give primarily the corresponding 1,2‐addition products containing a new PC bond. The first examples of transition‐metal‐catalyzed phosphinoborations of C‐C multiple bonds in which PC and BC bonds are formed in a single step are also disclosed; allenes react by a highly regioselective 1,2‐addition whereas terminal alkynes
报道了含有单个PB键的膦基硼酸酯的合成,以及对一系列有机底物的初步反应性研究。这些化合物很容易加到醛,酮,醛亚胺和α,β-不饱和烯酮上,从而主要生成相应的1,2-加成产物,其中含有一个新的PC键。还公开了在单个步骤中形成PC和BC键的C-C多键过渡金属催化的膦硼酸酯化的第一个例子;丙二烯通过高度区域选择性1,2-加成反应,而末端炔烃则进行正式的1,1-加成。
