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

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.
