Ultrasound assisted direct oxidative esterification of aldehydes and alcohols using graphite oxide and Oxone

• Direct oxidative esterification of aldehydes and alcohols is described.
• Sonochemical procedure for this transformation using graphite oxide and Oxone is developed.
• The protocol is advantageous as it takes place under mild conditions, in short reaction times and in good to high yields.

A sonochemical procedure for direct oxidative esterification of aldehydes and alcohols using graphite oxide and Oxone in an alcoholic solvent is described. Mild reaction conditions, short reaction times, cost-effectiveness, and facile isolation of the products make the present system as a practical method.
