nature was synthesized with melting point of 76 °C by a facile method. The synthesized [Caff‐TEA]+[ZnBr3]− has high catalytic activity as both of catalyst and solvent in condensation reactions for the synthesis of benzylidenes, bis‐hydroxyenones and xanthenes. Synthesized IL was characterized by proton nuclearmagneticresonance (1HNMR), Fourier transform infrared spectroscopy (FT‐IR), X‐ray diffraction

develop a new l-proline-Brønsted acid deep eutectic mixture (DEM)-driven straightforward protocol for the synthesis of (aryl/heteroarylmethylene)bis(3-hydroxy-5,5-dimethylcyclo-hexenone) derivatives with broad functional group compatibility using one-pot consecutive Claisen–Schmidt and Michaeladditionreactions. These derivatives are obtained under very mild reaction conditions with good yields (65–92%)
