Cobalt complex catalyzed atom-economical synthesis of quinoxaline, quinoline and 2-alkylaminoquinoline derivatives
A new phosphine-free Co (II) complex-catalyzed synthesis of various quinoxalines via
dehydrogenative coupling of vicinal diols with both o-phenylenediamines and 2-
nitroanilines is reported. This complex was also effective for the synthesis of quinolines. The
practical aspect of this catalytic system was revealed by the one-pot synthesis of 2-
alkylaminoquinolines.
