Abstract

Acceptorless dehydrogenative coupling of 2-aminobenzylamine with benzyl alcohol and 2-aminobenzylalcohol with benzonitrile enables the synthesis of quinazolines. The reactions are catalyzed by cheap and easy to prepare nickel catalysts, containing tetraaza macrocyclic ligands. A wide variety of substituted quinazolines were synthesized in good yields.
