✦ Synopsis

Hydrolytically stable borane-amines can be activated in situ through palladium catalysis and perform reductions not possible otherwise. Hence, borane-trimethylamine is an efficient hydrogen-transfer reagent for the open vessel reduction of nitroaryls to anilines. Likewise, the palladium catalyzed methanolysis/decomplexation of stable borane-amine adducts is accelerated by the action of nitrobenzene.
