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...

Single-molecule spectroscopy is used to gain insights into the click chemistry reaction photocatalyzed by copper. We show that CuxO@Nb2O5 catalysts can act as truly heterogeneous photocatalysts and that the amine plays an important role in the comple...

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...

Reduced graphene oxide modified by pulsed laser ablation causes water splitting under visible light illumination (532 nm). When the light source is a pulsed laser, water splitting is accompanied by carbon gasification (CO formation); however, convent...
