Abstract

Abstract: The AIC1, and BF,, as well as 65% HPF6, catalyzed Friedel-Crafts alkylation of anisole with alkyl halides and alcohols was investigated. The alkylation of anisole with lower catalyst concentrations under mild conditions shows predominant ortho/para directing effect generally with a ratio of-2: 1, with the amount of meta isomer uniformly less than 3%. With “swamping” catalyst conditions the amount of meta substitution in methylation and ...
