A convenient and eco-friendly nickel-catalyzed synthesis of quinoline and quinoxaline via double dehydrogenative coupling starting from 2-aminobenzyl alcohol/1-phenylethanol and diamine/diol, respectively, operates at mild reaction temperatures. The inexpensive molecularly defined catalyst can easly be regenerated under aerobic/O2 oxidation.
