A convenient method for the benzylation of chelated phenolic groups: Use of tetra-n-butylammonium iodide as a catalyst

摘要

Benzylation of chelated phenolic groups in different classes of polyphenolics 1-5 has been carried out, in quantitative yields efficiently by making use of tetra-n-chloride-acetone-potassium carbonate. The procedure for working up the reaction mixture has also been improved by avoiding the step involving steam distillation required for removal of benzyl chloride after the reaction is over.
