Zirconyl Chloride: A Useful Catalyst in the Pechmann Coumarin Synthesis

Abstract

Coumarin derivatives were prepared using zirconyl chloride octahydrate (1%) as a Pechmann catalyst, either neat or in some cases employing small volumes of ethanol as solvent. As result of this work, coumarins were obtained in moderate to good yields.

Key words

coumarins - zirconyl chloride - Pechmann reaction
