Allgemeine Beschreibung

Phenyl benzoate is a phenyl ester of benzoic acid. Crystal structure of phenyl benzoate has been determined from 844 microdensitometer-measured intensities. All bond lengths and angles were reported to be normal. Phenyl benzoate undergoes Fries rearrangement catalyzed by heteropoly acids to yield the acylated phenols and esters.

Phenyl benzoate serves as a precursor that undergoes the intramolecular biaryl coupling reaction to produce the intermediate for the synthesis of (−)-steganone.

Anwendung

Phenyl benzoate was used in the synthesis of soluble polyimides using dianhydride/diamine derivatives.

A decarbonylative C-H coupling of azoles and aromatic esters by palladium catalysis is described. Our previously reported Ni-catalyzed C-H coupling of azoles and aromatic esters has a significant drawback regarding the substrate scope. Herein, we employ palladium catalysis instead of

Fries Rearrangement

The Fries rearrangement reaction is an organic name reaction which involves the conversion of phenolic esters into hydroxyaryl ketones on heating in the presence of a catalyst. Suitable catalysts for this reaction are Brønsted or Lewis acids such as HF, AlCl3, BF3, TiCl4, or SnCl4. The Fries rearrangement reaction is an ortho, para-selective reaction, and is used in the preparation of acyl phenols. This organic reaction has been named after German chemist Karl Theophil Fries.
