Abstract

A nickel-catalyzed cross-coupling reaction between aryltitanium(IV) alkoxides and various functionalized aryl halides is described. The reaction requires Ni(acac)2 (0.5 mol%), a phosphine or an N-heterocyclic carbene ligand (NHC ligand; 0.5-1.0 mol%) and proceeds at 25 °C within 1-24 hours.
