The Effect of Co‐catalyst in the Friedel–Crafts Reaction in Synthesis of Diaryl‐naphth‐1‐yl‐methane Derivatives

Abstract

Synthesis of substituted diaryl‐naphth‐1‐yl‐methane has been carried out by Friedel–Crafts reaction of aryl naphth‐1‐yl methanol with substituted phenols. During the course of this reaction using AlCl₃ as catalyst some rearrangements occurred, resulting in the formation of a complex mixture of products. Use of CTMS, ZrCl₄, and SnCl₄ as a co‐catalyst in combination with AlCl₃ enhanced the formation of the para alkylated product.
