Direct conversion of phenols into amides and esters of benzoic acid. (2013). Direct conversion of phenols into amides and esters of benzoic acid. Retrieved from http://purl.flvc.org/fsu/fd/FSU_uspto_8410303
A method is provided for the preparation of an aromatic carboxylic acid aryl ester or an N-aryl aromatic carboxamide. The method comprises contacting an O,O-diaryl thiocarbonate or an O-aryl-N-aryl thiocarbamate with a reactant that regioselectively reacts with sulfur, which contact causes an O-neophyl rearrangement, thereby forming either the aromatic carboxylic acid aryl ester or the N-aryl aromatic carboxamide, respectively.
