Abstract
The catalytic hydroboration of ketones, aldehydes, and imines with pinacol borane and Ni(bpy)(cod) has been demonstrated in benzene at room temperature and low catalyst loadings (0.03-0.3 mol-%). Spectroscopic and structural evidence support the formulation of Ni(bpy)(cod) as containing a NiI cation and a bpy·- ligand. The Ni(bpy)(cod) complex reacts quickly with ketonic substrates to form an adduct that appears to function as an entryway into catalytic activity.
