Abstract

In the present study, successful implementation of grinding technique and camphor sulphonic acid (CSA) as a catalyst, has been demonstrated for the rapid synthesis of 12-aryl-9,9-dimethyl-8,9,10,12-tetrahydrobenzo[a]xanthen-11- ones at ambient temperatures, avoiding excessive/wasteful heating.

Keywords: Camphor sulphonic acid (CSA), clean synthesis, green chemistry, grinding technique, solvent-free synthesis, xanthen-11-one derivatives, dodecatungustophosphoric acid, strontium triflate, iodine, ammonium fluoride
