Abstract

Ionic liquids are often used together with dichloromethane in different reactions. This combination can be problematic because the use of ionic liquids with a carboxylic acid as an anion and dichloromethane can lead to the formation of methylene diesters. The reaction of trioctylmethylammonium benzoate with dichloromethane was studied, where the ionic liquid acted as reactant, solvent and catalyst. The molecular structure of methylene dibenzoate was determined by X-ray crystallography.
