One-Pot Synthesis of Benzoxanthenes in Solvent Free Condition using Chloroaluminate Ionic Liquids as Catalyst
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2013, Vol 5, Issue 1
Abstract
A mild and efficient method has been developed for the preparation of 14-aryl-14H dibenzo[a,j]xanthenes from one-pot condensation of aldehydes with β-naphthol using catalytic amount of Chloroaluminate ionic liquid (imidazolium chloride·3AlCl3 or pyridiniumchloride·3AlCl3) under thermal solvent-free conditions. Excellent yields, short reaction times, easy workup and reusability of the catalyst as well as solvent free conditions are advantages of this procedure.
