Studies on the water-promoted synthesis of chalcones. A contribution to the green synthesis of organic compounds

Supporting information. Herein, a methodology for the water-promoted synthesis of chalcones is presented, a green methodology, that pretends adding to the new ecologic tendencies and showing the capabilities and limitations of water to promoting the synthesis of organic molecules. Reaction proceeds at room temperature using only KOH (a green base and shown a broad applicability, since 38 derivatives were prepared in good to excellent yields (up to 98%). In addition, most compounds were recovered pure enough by simply filtration and water washing.
