A new, transition-metal-free, effective method for aromatic esterification of amides with organoboronic acids has been developed. A wide range of benzoate derivatives were obtained with yields ranging from moderate to good. The catalytic reaction shows a broad substrate scope and excellent functional group tolerance. Conceptually, DMAP mediates the reaction and is crucial for this transformation.

A new acyl-acyl exchange reaction has been developed for the formation of aryl esters from primary aryl amides. The reaction could occur under mild reaction conditions with catalytic quantities of K2CO3, and could afford moderate to good yields of the desired products.
Study on the aromatic transesterification reaction catalyzed by phosphotungstic acid
He, Hong-Qiang,Chang, Yu-Wei,Xu, Wei-Ming
supporting information, p. 280 - 282 (2015/06/22)
A practical phosphotungstic acid-catalyzed aromatic transesterification reaction for the preparation of aryl benzoates has been developed. The transesterification method avoids the oxidation of the corresponding phenols to quinone compounds with easy operations, environmentally benign conditions and high yields of the products. It is noteworthy that in this process phosphotungstic acid can be reused and recycled.
The chemoselective preparation of the substituted phenyl benzoates using re-Y zeolite as catalyst
Ding, Yixiang,Wu, Rui,Lin, Qiang
, p. 2149 - 2153 (2007/10/03)
A practical and chemoselective method for the synthesis of substituted phenyl benzoates using rare earth zeolite as catalyst was described, its recycle procedure offers high total yield.
BeCl2 as a new highly selective reagent for dealkylation of aryl-methyl ethers
Sharghi, Hashem,Tamaddon, Fatemeh
, p. 13623 - 13640 (2007/10/03)
An efficient and simple method is introduced for the selective removal of methyl group from poly aryl-methyl ethers, in some important derivatives of benzophenones, xanthones, anthraquinones, aryl esters, benzamides and nitroanisoles with BeCl2.
