Esters aromatic, aerobic oxidation

Aerobic oxidation of aromatic aldehydes with boronic acid to yield ester is catalysed by A-heterocyclic carbenes. The reaction proceeds under mild conditions with good to excellent yields. On the basis of experiments with 02, a mechanism (Scheme 31) has been postulated. ... [Pg.131]

A wide range of aromatic esters has been prepared in up to 99% yield by NHC-catalysed aerobic reaction of aromatic aldehydes with aryl boronic acids (ArB(OH)2) under mild conditions. By appropriate selection of the NHC catalyst, a-unbranched aldehydes can be converted to amide, ester, or carboxylic acid through oxidation by NCS in CH2Cl2. ... [Pg.38]
