Abstract
A series of oligo(ethylene glycols) was efficiently tosylated by ultrasound procedure within dichloromethane in the presence of triethylamine. Results show that sonochemical synthesis of oligo(ethylene glycol) ditosylates has a double advantage since it does not use catalysts and it drastically reduces the reaction time. This straightforward method represents an eco-friendly alternative to the traditional tosylation by pyridine synthesis.
► Optimized synthesis of alcohol ditosylate under ultrasound. ► Substitution of the traditional pyridine method. ► Reduction of the reaction time by a factor 8.
