Abstract

Onion waste catalyzed synthesis of flavones derived from chalcones to unveil the pathway of green catalysis

Suman Sangwan, Rajvir Singh, Susheel Gulati and Suprita

Efficient, facile, and alternate synthesis of biologically potential flavones is reported. The 2-hydroxychalcones derived from condensation between acetophenones and salicylaldehyde in presence of Silica.SO3H underwent oxidative cyclization in the presence of onion waste extract with iodine, generating useful flavones under solvent-free conditions. The solid catalyst has been characterized by SEM, TEM and X-ray diffraction method. Reported compounds synthesized in good yields and their mechanisms of formation is explained.
