CATALYST SYSTEM FOR AEROBIC DEHYDROGENATION OF TETRAHYDROQUINOLINE DERIVATIVES

摘要

The present invention relates to a catalyst system for aerobic dehydrogenation of tetrahydroquinoline derivatives, and more particularly, to azodicarboxylate compounds under oxygen conditions; Pyridine-based compounds; And dehydrogenation of the tetrahydroquinoline derivatives to the corresponding quinoline derivatives using a catalyst system comprising copper halides, using a catalytic amount of azo compound and oxygen as the final oxidant to yield high yields of quinoline derivatives for various substrates. Can optionally be obtained.
