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与他们的新氯化衍生物10 - 13。这些化合物可以在温和的条件下,通过一锅法以令人满意的收率,从市售可得的安全起始原料获得。在该反应中,试剂PCl 3和AlCl 3在获得产物中都起着基本作用,该方法可能适用于其他4-烷氧基硝基苯。
