Expanding the Color Space in the Two-Color Heterogeneous Photocatalysis of Ullmann C–C Coupling Reactions (2018)
Journal Article
Marina, N., Lanterna, A. E., & Scaiano, J. C. (2018). Expanding the Color Space in the Two-Color Heterogeneous Photocatalysis of Ullmann C–C Coupling Reactions. ACS Catalysis, 8(8), 7593-7597. https://doi.org/10.1021/acscatal.8b02026

The Ullmann reaction can be heterogeneously photocatalyzed by UV excitation of Pd@TiO2. While a similar dose of visible light does not initiate the reaction, combination with UV light enhances activity and selectivity toward cross-combination product...

We use the aurophilic interactions shown by lanthanides to overcome the sulfur–gold interaction. UV–vis and X-ray photoelectron spectroscopy confirm that yttrium or lanthanide chlorides easily displace sulfur ligands from the surface of thiol-stabili...
