Reactions of CH acids with the Michael acceptors in the presence of potassium carbonate 2*. Difluoroborines of 6-acetyl-2-cyclohexenones: synthesis, structure, and luminescence properties

摘要

New 2-cyclohexenone derivatives were synthesized via the Michael reaction in the presence of potassium carbonate. These derivatives containing the acetyl substituent in position 6 are of special interest due to the ability to form boron chelate complexes, 1,3-dioxaborines, possessing luminescence properties. The dependence of the position of the absorption and luminescence absorption band maxima on the donor properties of the substituents was found.
