Directing group assisted copper-mediated aroylation of phenols using 2-bromoacetophenonesElectronic supplementary information (ESI) available: Experimental procedures, characterization data, 1H and 13C NMR spectra of synthesized compounds. See DOI: 10.1039/c7cc05383e

A new directing group assisted method for the synthesis of aryl esters is described. In this Cu( ii )-mediated reaction, 2-formylphenols and 2-acetylphenols are easily converted into aryl esters via treatment with a new aroylating agent 2-bromoacetophenone. In addition, a new external bromine free m...

Description
Summary:A new directing group assisted method for the synthesis of aryl esters is described. In this Cu( ii )-mediated reaction, 2-formylphenols and 2-acetylphenols are easily converted into aryl esters via treatment with a new aroylating agent 2-bromoacetophenone. In addition, a new external bromine free method for the synthesis of important synthons 2,2-dibromoacetophenones from 2-bromoacetophenones is described. A new method for a directing group-assisted synthesis of aryl esters and an external bromine free synthesis of 2,2-dibromoacetophenones is described.
