Abstract
The reaction between quinoxaline and benzopyridine in acetic anhydride in the presence of zinc dust gives a quinoxaline anion and a benzopyridine N-acetyl radical, which recombine to give the previously unknown N-acetyl dihydrobenzo-pyridine derivative of 1,2-dihydroquinoxaline. Under these conditions, quinoxaline alone gives 1,4-diacetyl-1,4-dihydroquinoxaline and 1-acetyl-2-(1,2-dihydroquinoxalyl-2)-1,2-dihydroquinoxaline.
