• The reactions of unactivated aryl halides with sodium methoxide in HMPA
  作者：L. Testaferri、M. Tiecco、M. Tingoli、D. Chianelli、M. Montanucci

  日期：——

  Sodium methoxide reacts with dichlorobenzenes in HMPA to give the chloroanisoles as a result of a SNAr process. Excess MeONa then effects the demethylation of the ethers to give the chlorophenols via an SN2 reaction. With tri- and tetrachlorobenzenes the initially formed chloroanisoles can be dealkylated to chlorophenols or can suffer further substitution to give the chlorodimethoxybenzenes; these

  由于S N Ar过程，甲醇钠与HMPA中的二氯苯反应生成氯茴香醚。然后过量的MeONa通过S N 2反应使醚脱甲基，得到氯酚。用三氯苯和四氯苯可以将最初形成的氯茴香醚脱烷基化为氯酚，或者可以进一步取代生成氯二甲氧基苯；它们与过量的MeONa反应，得到氯甲氧基苯酚。在取代基的电子效应的基础上，介绍并讨论了用二，三和四氯苯的各种异构体获得的结果。
