4-nitroalkoxybenzenes 7 and PCl3/AlCl3, when carried out in appropriate molar ratio, gives a prevalent formation of diazenes 8 and 2,7-dialkoxyphenazines 9 with their new chlorinated derivatives 10–13. These compounds are obtained, in satisfactory yield, in a one-pot procedure, in mild conditions, from commercially available and safe starting materials. In this reaction both the reagents PCl3 and AlCl3 play a fundamental
4- nitroalkoxybenzenes之间的反应7和PCL 3 /的AlCl 3,在合适的摩尔比进行,给出了
二氮烯的一种普遍的形成8和2,7- dialkoxyphenazines 9与他们的新
