2,5-Diarylamino-N-α(Β)-naphthyl-1,4-benzoquinone monoimines undergo oxidative cyclization to give benzannelated phenazinone derivatives. The effect of an N-aryl fragment on the ease of cyclization decreases in the order N-Β-naphthyl>N-α-naphthyl>N-phenyl. 2-Arylamino-N-phenyl-1,4-naphthoquinone monoimines do not undergo oxidative cyclization to phenazinones.
