The selective esterification of carboxylic acid derivatives with a variety of alkyl halides was carried out using ionic liquid as solvent in the presence of triethylamine. The reaction was found to proceed under relatively mild conditions with excellent conversions (up to 99%) and selectivities. The ionic liquid was recycled and reused. TUeBITAK.

Terephthalic acid can be readily converted to the corresponding monoalkyl terephthalate in high yield, via a two-step procedure. This method is advantageously compared to the more representative methods described in the literature. The purification of the expected monoester, a crucial problem for this synthetic pathway, is discussed, and an original procedure has been developed. Copyright Taylor & Francis Group, LLC.
A mild and selective method for the hydrolysis of esters with trimethyltin hydroxide

Mild, selective, and efficient: A new method that involves the use of trimethyltin hydroxide for the hydrolysis of specific ester groups allows chemists to steer clear of unwanted elimination reactions and epimerizations. For example, the conversion of ester 1 into carboxylic acid 2 takes place under mild conditions, with nearly complete retention of stereochemical integrity. 1,2-DCE = 1,2-dichloroethane.
