Zinc chloride (ZnCl2) is used as an efficient catalyst condensation of 4-hydroxycoumarin and with various aromatic aldehydes leading to the formation of biscoumarin derivatives. Easy isolation of the products, short reaction times, excellent yields and reusability of catalyst was theadvantage of thismethod.
