Flash vacuum pyrolysis of the title compounds at 600 deg C gives quinoxalines and arylamines, together with small quantities of nitriles, diarylamines, azobenzenes, and formamidines.The mechanism involves homolytic cleavage of the N-N bond to generate a conjugated iminyl radical, which can either cyclise to a quinoxaline, or fragment to simpler radicals which lead to the minor products by coupling reactions.
