- Abstract
Use of imidazolium ionic liquids [Bmim][CF3COO] and [Bmim]OH as a catalyst for synthesis of 3-arylidene(thio)chroman4-ones by the condensation of (thio)chroman-4-ones and aromatic aldehydes under microwave irradiation conditions. A series of 3-arylidene(thio)chroman-4-ones were obtained as the only product and considerable increase of yield was founded within short time. The products 3-arylidene(thio)chromanones were assigned the (E)-configuration based on 1H NMR spectroscopic data.
