The reaction of anisole with propylene oxide by aluminum chloride has been studied in various kinds of solvents. While the normal Friedel-Crafts reaction yielded 2-(methoxyphenyl)-1-propanols, 1,1-bis(methoxyphenyl)-propanes were also formed in this reaction; these were not obtained by the subsequent reaction of mono(methoxyphenyl) products with another anisole. The yields of 1,1-bis(methoxyphenyl)propanes
苯甲醚与环氧丙烷在氯化铝作用下的反应已在各种溶剂中进行了研究。虽然正常的 Friedel-Crafts 反应产生 2-(甲氧基苯基)-1-丙醇,但在该反应中也形成 1,1-双(甲氧基苯基)-丙烷;这些不是通过单(甲氧基苯基)产物与另一种苯甲醚的后续反应获得的。1,1-双(甲氧基苯基)丙烷的产率通过增加溶剂的碱性而增加。1,1-双(甲氧基苯基)丙烷的形成机制可以通过环氧化物异构化为醛和随后与苯甲醚缩合来解释。各种环氧化物也在硝基甲烷中生成 1,1-双(甲氧基苯基)烷烃。
