A kinetic study of the reaction of coumarin derivatives with Vilsmeier-Haack ( V H ) reagent 1 I I DMF-POCI,) in various solvent media revealed second-order kinetics with a first-order in /Substratel and first-order in IVH reagent). The reaction rates altered nonlinearly with an increase in the diel
