This method involved solvent-free reaction conditions under microwave irradiation in the presence of a clay-based catalyst, and afforded the target compounds in good yields and short reaction times. Furthermore, the same conditions allowed the synthesis of symmetrical, diarylmethylene-α,β-unsaturated ketones from aromatic aldehydes and ketones.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttps://doi.org/10.3390/molecules19067317https://www.mdpi.com/1420-3049/19/6/7317open access547heterogenous catalysisclays as catalystsLewis acidscondensation reactionsgreen chemistryaldehydesenonesQuímica orgánica (Farmacia)
