The reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. This method is also simple and inexpensive and leads to high yield of products in short reaction times. IS - 2 PB - OICC Press KW - Silica gel, Catalyst, Aldehyde, Biscoumarin, Water EN -
