Abstract
Xanthenedione derivatives were prepared through the condensation reaction of aromatic aldehydes with 5,5-dimethyl-1,3-cyclohexanedione promoted by 1-methyl-3-(3-sulfopropyl)imidazolium methyl sulphate, the reaction time was 20-40 min with the yields between 83.0-95.1 %. It is shown that the proposed method is fast, high efficient and environmentally benign.
