If you wonder about how to harness innate excited-state reactivity in TM photocatalysis to design new synthetic methods, you can find some guidelines and a rationalization attending to orbitals in this Perspective, just published in @ACSCatalysis : pubs.acs.org/doi/10.1021/acs… (1/3)

Catalysis in the Excited State: Bringing Innate Transition Metal Photochemistry into Play

Transition metal catalysis is an indispensable tool for organic synthesis that has been harnessed, modulated, and perfected for many decades by careful selection of metal centers and ligands, giving...

Our latest publication in @Chem_CP demonstrates the umpolung Birch-like reduction of naphthalenes by photoexcitation employing a very mild acidic solvent (HFIP) and amine-boranes as reductants with high functional group compatibility ⬇️🔗 cell.com/chem/fulltext/S2451…

Excited-state protonation and reduction enable the umpolung Birch reduction of naphthalenes

The Birch reaction is a key reaction for increasing sp3 content in organic molecules, but it traditionally requires strong reductants. This article presents a new strategy that reverses the nature of...

In this strategy we explore the transient increase of the aromatic basicity after photoexcitation to promote the protonation step, forming an intermediate carbocation which is trapped in situ with Et3N-BH3, by-passing the very low redox potential of aromatics.

Excited to share our latest work on chemical permutation, now published in @Nature! Using photochemical conditions, we've developed a method to selectively and predictably transform the structures of thiazoles, isothiazoles, and other azole systems.

Building on pioneering studies by Pavlik, Maeda, and Vernin, this research demonstrates a way to reconfigure heteroaromatic structures—enabling one ring system to serve as a starting material for synthesizing another.
