KULKARNI, Pramod. Calcium Chloride/HCl an Efficient Co-Catalytic System for Synthesis Xanthene under Microwave Condition. J. Mex. Chem. Soc [online]. 2018, vol.62, n.1, 00008. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v62i1.582.

Calcium chloride along with one drop of concentrated HCl is a facile and efficient catalyst for the synthesis of aryl 14H-dibenzo[a,j] xanthene derivatives via one-pot condensation of various substituted benzaldehydes and β-naphthol under microwave and solvent-free conditions. The advantages offered by the present protocol include shorter reaction time, good-to-excellent yields, operational simplicity, cost-effectiveness, and easily available catalysts.

Keywords : Calcium chloride; microwave; xanthenes; condensation reaction; β-naphthol.
