Silica-ZnCl(2): An Efficient Catalyst for the Synthesis of 4-Methylcoumarins
Silica-ZnCl(2) has been found to be an efficient and eco-friendly catalyst for the synthesis of substituted 4-methylcoumarins from ethyl acetoacetate and substituted phenols under “neat” conditions in an oil bath at 80°C. The experimental procedure is simple, includes shorter reaction times (15–65 m...
