An efficient general method for esterification of aromatic carboxylic acids

Hosangadi, Bhaskar D.,Dave, Rajesh H.

, p. 6375 - 6378 (1996)

Treatment of a variety of aromatic carboxylic acids with alcohols in the presence of thionyl chloride results in excellent yields of corresponding esters. This esterification system is compatible with a wide assortment of functional groups.

2-Iodoxybenzoic acid-mediated transformation of halogenated hydrocarbon in the presence of tetraethyl ammonium bromide

Zhang, Yuan,Han, Jianlei,Xu, Yanjun,Wei, Yuping

experimental part, p. 303 - 307 (2012/09/25)

2-Iodoxybenzoic acid (IBX) has been shown to react with alkyl halides in the presence of tetraethyl ammonium bromide to give 2-iodobenzoate esters. Most of the monohalides and dihalides reacted easily with moderate to good yields. The 2-iodobenzoate ester
