Microwave assisted nano-coconut shell-BF3 as heterogenous new catalyst for multicomponent synthesis of 4H-chromene derivatives abstract

The reaction of nano-coconut shell and boron trifluoride in diethyl ether gave nano-coconut shell-BF3. Also nanococonut shell-BF3 has been characterized by Fourier transform infrared spectroscopy (FT-IR), Field Emission Scanning Electron Microscopy (FESEM) and transmission electron microscopy (TEM). Nano-coconut shell-BF3 hasbeen applied as a new catalyst for synthesis of 4H-chromene derivatives from the simple one-pot reaction between aryl aldehydes, cyclic 1,3-diketone and malononitrile. Cleanliness, simple methodology, short time, and excellent yields of products are some advantages of this method.
