Efficient esterification of carboxylic acids and phosphonic acids with trialkyl orthoacetate in ionic liquid

Yoshino, Tomonori,Imori, Satomi,Togo, Hideo

, p. 1309 - 1317 (2006)

An operationally simple, inexpensive, efficient, and environmentally friendly esterification of various carboxylic acids, phosphonic acids, and phosphinic acids with triethyl orthoacetate or trimethyl orthoacetate under neutral conditions in a typical room temperature ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate, was successfully carried out to provide the corresponding ethyl esters or methyl esters in high yields.
