An unusual degree of functional group compatibility for imine addition reactions was observed in the assembly of allylic amines from alkynes, imines, and organoboron reagents (boronic acids or boranes) by using a catalyst derived from [Ni(cod)2] and (c-C5H9)3P—this catalytic three-component process (see scheme) is tolerant of ketones, esters, and hydroxylic solvents.
