A silane-promoted nickel-catalyzed amination of aryl chlorides with a catalytic amount of Ni(acac)2 and 3,5,6,8-tetrabromo-1,10-phenanthroline as ligand in the presence of polymethylhydrosiloxane gives the desired (het)arylamines in good yields. The reaction is sensitive to the nature and amount of the silane promoter.
