We describe herein the use of glycerol as an efficient and a recyclablesolvent in the thioacetalization of aldehydes and ketones. The catalyst-free reactions proceed easily usingglycerol at 90 °C and the corresponding thioacetals were obtained in good to excellent yields. Glycerol was recovered and utilized for further thioacetalization reactions.
