Selective Fries Rearrangement Catalyzed by Zinc Powder

Abstract

Zinc powder in the presence of N,N-dimethylformamide efficiently catalyzes the selective Fries rearrangement of acetylated phenols under microwave heating or with conventional heating using an oil bath. In some cases different products were obtained using microwave heating and conventional heating. Selective migration of the acyl group has been noted with good yields.

Keywords

acetylated phenols - zinc powder - Fries rearrangement - microwave activation - selectivity
