摘要：

The novel efficient procedure has been developed for the oxathioacetalization of carbonyl compounds and 2-mercaptoethanol using the novel carbon-based sulfonic acid as catalyst under solvent-free condition at room temperature. The results showed that the novel catalyst was very efficient for the reactions with good to excellent yields in short time. The novel catalyst owned many advantages such as operational simplicity, without need of any solvent, small amount of usage, low cost of the catalyst used, high yields, applicability to large-scale reactions, reusability and chemoselectivity over the traditional catalysts, which made the catalyst one of the best choices for the reactions.
