Abstract

We demonstrate an efficient protocol for the chemoselective hydroboration of organic nitriles with pinacolborane (HBpin) and catecholborane (HBcat) using aluminum alkyl complex [κ2‐{2‐F‐C6H4NP(Se)Ph2}2Al‐(Me)] as a pre‐catalyst to afford diboryl amines under solvent‐free and mild conditions (60°C) in high yield. The aluminum complex was prepared by the reaction of [2‐F‐C6H4NHP(Se)Ph2] and trimethylaluminum in toluene. The solid‐state structure of Al complex is established. Nitriles with a wide array of electron‐withdrawing and electron‐donating functional groups were easily converted to the desired products through the formation of aluminum hydride as an active species. A kinetic study of the catalytic reaction is also reported.
