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.
