In a process for the accelerated reduction of organic substrates, selected from the group consisting of ester, amides, nitriles, acids, ketones, imines or mixtures thereof, the substrates are reacted with an amine borane, sulfide borane or ether borane complex as a borane source in the presence of organic accelerator compounds containing both Lewis acidic and Lewis basic sites in their structure, of which the Lewis acidic site can coordinate with the carbonyl or nitrile or imine group of the substrate and the Lewis basic site can coordinate with the borane.
在一种用于有机底物的加速还原过程中,所选的底物来自酯、酰胺、腈、酸、酮、亚胺或它们的混合物组成的群体,底物与胺硼烷、硫硼烷或醚硼烷复合物作为硼源在有机加速剂化合物的存在下发生反应,这些有机加速剂化合物的结构中含有既具有Lewis酸性又具有Lewis碱性位点,其中Lewis酸性位点可以与底物的羰基、腈基或亚胺基协同配位,而Lewis碱性位点可以与硼烷协同配位。
