N2 - An efficient and convenient approach to the synthesis of 9-aryl-2, 3, 4, 5, 6, 7-hexahydro-2H-Xanthene-1, 8-dionc by condensation of 1, 3-cyclohexanedione with aromatic aldehydes catalyzed by acid ionic liquid 1-methyllimidazolium hydrogen sulphate ([Hmim]HSO4) is described. This method provides many advantages such as being environmentally benign, simple work-up, short reaction times, obtaining in good to excellent yields with high purity, and the reusability of ionic liquids.
