Highly Efficient Transfer Hydrogenation of Alkenes With Ammonia Borane Mediated by a Simple Ni(II) Catalyst System

A practical nickel platform for transfer hydrogenation (TH) of alkenes using ammonia borane (AB) is described. With NiCl 2 ·6H 2 O/ethylenediamine ( L2 ) at 25–50 °C, aromatic and aliphatic alkenes reduce rapidly and α,β‐unsaturated esters undergo chemoselective C═C hydrogenation; at low loading the system achi...
