ChemInform Abstract: Trimethylamine-Borane - a Useful Reagent in the One-Pot Preparation of Carboxylic Esters from Carboxylic Acids

Autor: Giuseppe Trapani, Gaetano Liso, Antonia Reho, Andrea Latrofa

Publikováno v: ChemInform. 22

The carboxylic esters (R 1 CO 2 CH 2 R 1 )and (R 1 CO 2 CH 2 R 2 ) are synthesized from alkyl or aryl carboxylic acids, a one-pot reaction involving in situ reduction followed by esterification, both steps are mediated by trimethymamine-borane.
