Abstract
- [Display omitted] • Heteroleptic copper complexes as efficient energy transfer photocatalysts. • The structure-activity-relationship of heteroleptic copper complexes was explored. • The high selectivity and good yield were obtained in the photodimerization. • The synthesis method has good universality for enones. The [2 + 2] photodimerization of chalcones, cinnamates and cinnamamides can be effectively catalyzed by heteroleptic copper(I) complexes. The reactions were carried out under mild reaction conditions and the products were obtained in 20–72% yield under visible light irradiation. The copper-based photocatalyst comprised of the rigid phenanthroline ligand with substituents at the 2,9-positions and the 4,7-positions showed high activity in the photodimerization via an energy transfer pathway.
