nickel-catalyzed synthesis of isoindolinones from imines, aryliodides, and CO. This reaction is catalyzed by Ni(1,5-cyclooctadiene)2 in concert with chloride salts and postulated to proceed via a tandem nickel-catalyzed carbonylation to form N-acyl iminium chloride salts, followed by a spontaneous nickel-catalyzed cyclization. A range of aryliodides and imines have been found to be viable substrates in

A nickel(0) catalyst effectively mediates the cyclization of N-benzoyl aminals in the presence of a stoichiometric Lewis acid. This method enables preparation of a variety of isoindolinones with substitution on the benzoyl fragment and C-3 carbon. This reaction likely proceeds via an α-amidoalkylnickel(II) intermediate, which then may cyclize via either an electrophilic aromatic substitution or an
