Year: 1993
Abstract:
The Mechanism of Fries Rearrangement and Acylation Reaction in Polyphosphoric Acid were studied...
Improvement of Selectivity in the Fries Rearrangement and Direct Acylation Reactions by Means of P2O5 / SiO2 Under Microwave Irradiation in Solvent-Free Media
Year: 2003
Abstract:
P2O5 / SiO2 was found to be an efficient new reagent in the Fries rearrangement of acyloxy benzene or naphthalene
derivatives and the direct acylation reactions of phenol and naphthol derivatives with carboxylic acids under...
