An Efficient and Simple Procedure for the Synthesis of 4-Substituted Coumarins by von-Pechmann Reaction using Mixture of FeCl3 and Tetrabutylammoniumbromide as Catalyst

Asitanga Ghosh


Abstract: von-Pechmann reaction is modified by using a cheap, easily available and a very effective Lewis acid catalyst - FeCl3. A series of 4-substituted coumarin derivatives have been prepared from a mixture of a phenol derivatives and ethyl acetoacetate using catalytic amount of FeCl3 in nitrobenzene in presence of phase transfer catalyst tetrabutylammoniumbromide


Keywords: von-Pechmann reaction, coumarin, phenol, ethyl acetoacetate and FeCl3 catalyst
