Quantitative NaH catalytic hydroboration of aldimines†
Abstract
The catalytic hydroboration of aldimines was demonstrated, with only 3 mol% NaH required for the quantitative production of secondary amines under minimal solvent conditions. In addition, chemoselective hydroboration in the presence of other reducible functional groups was achieved. DFT calculations were then used to propose a reaction mechanism for imine hydroboration.
