Abstract The catalytic hydrodechlorination of BCl 3 with molecular hydrogen in the presence of tertiary amines is a viable strategy for the energy-efficient generation of valuable B–H bonds. A mechanistic study based on experiments with isolated intermediates and deuterium labeling experiments is presented. The occurrence of the rate-limiting reverse reaction from the insoluble Et 3 NHCl adduct was identified as a major cause of low Et 3 ...
