摘要：

Sulfated zirconia (1%) was employed as Pechmann's catalyst without solvent or in some cases using a small amount of ethanol to obtain coumarins in moderate to good yields. With this procedure, no significant acidic waste was obtained and an environmental friendly alternative to obtain coumarins is provided. (c) 2006 Published by Elsevier Ltd.
