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。
The present invention discloses compounds of Formula (I): wherein the variables in Formula (I) are defined as described herein. Also disclosed are pharmaceutical compositions containing such compounds and methods for using the compounds of Formula (I) in the prevention or treatment of HCV infection.
Discovery of practical production processes for arylsulfur pentafluorides and their higher homologues, bis- and tris(sulfur pentafluorides): Beginning of a new era of “super-trifluoromethyl” arene chemistry and its industry

Various arylsulfur pentafluorides, ArSF(5), have long been desired in both academic and industrial areas, and ArSF(5) compounds have attracted considerable interest in many areas such as medicines, agrochemicals, and other new materials, since the highly stable SF(5) group is considered a "super-trifluoromethyl group" due to its significantly higher electronegativity and lipophilicity.
