Dialkyl Imidazolium Benzoates – Room Temperature Ionic Liquids Useful in the Peracetylation and Perbenzoylation of Simple and Sulfated Saccharides

Abstract

Dialkyl imidazolium benzoates, room temp. ionic liqs. including 1-ethyl-3-Me imidazolium benzoate, 1-butyl-3-Me imidazolium benzoate and 1-hexyl-3-Me imidazolium benzoate were used in the peracetylation and perbenzoylation of several simple and sulfated carbohydrates. Org. solvents and catalysts were not required in the syntheses and these ionic liqs. gave excellent yields in short reaction times.
