abstract

a simple and environmentally benign procedure for the synthesis of 14-aryl-14h-dibenzo[a,j]xanthenes by a one-pot condensation of 2-naphthol with aromatic aldehyde in the presence of [et3nh][hso4] as an acidic ionic liquid catalyst under solvent-free conditions has been developed. the reaction work-up is very simple and the catalyst can be easily separated from the reaction mixture and reused several times in subsequent reactions.
