An efficient diazo-transfer reaction of phenol is described. o-Quinone diazide (diazoquione) were synthesized from phenol by the diazo-transfer reaction using 2-azido-1,3-bis(2,6-diisopropylphenyl)imidazolium hexafluorophosphate (IPrAP), which is safe and stable crystalline, in MeOH in the presence of iPr2NH or DMAP. In addition, diazoquinones reacted with sodium azide smoothly in 2-methoxyethanol
描述了苯酚的有效重氮转移反应。邻-醌二叠氮化物(diazoquione)是由苯酚通过重氮转移反应,使用 2-叠氮基-1,3-双(2,6-二异丙基苯基)咪唑六氟磷酸盐 (IPrAP) 合成的,它是一种安全稳定的结晶,在 MeOH 中i Pr 2 NH 或 DMAP的存在。此外,重氮醌与叠氮化钠在 2-甲氧基乙醇中顺利反应,以高收率得到叠氮苯酚。
