摘要：
Oxalic acid was found to be an efficient catalyst for Pechmann condensation, which includes the reaction between phenols and P-keto esters leading to formation of coumarin derivatives. The advantages of present methods are the use of cheap and easy available catalyst, solvent-free reaction conditions, better yields and shorter reaction time. (c) 2007 Devanand B. Shinde.
