demonstrated by conducting a series of selective reductions of alkynes and alkenes, and hydrogen–deuterium exchange reactions using two‐chamber reactors. Finally, as the water reduction reaction generates an intermediate borohydride species, a range of aldehydes and ketones were reduced by using water as the hydride source.
合成了一系列结晶的sp 3 -sp 3 diboron(4)化合物,它们显示出促进形成二氢的水的简便还原。通过对乙炔和烯烃进行一系列的选择性还原,以及使用两室反应器进行氢-氘交换反应,证明了这些二硼作为简单有效的二氢和二氘源的应用。最后,由于水还原反应生成了中间的硼氢化物,通过使用水作为氢化物源,可以还原一系列醛和酮。
