NSF Fellowships

Congratulations to Yoon lab second-years Grace and Matt for their honorable mension and fellowship, respectively, from the NSF GFRP! Two of 21 (!?!?!?!) to UW-Madison Chemistry this year!

Bronsted acid triplet activation

Evan and Hoimin’s discovery of Bronsted acid catalyzed triplet sensitization is online at Chem Sci. This third chapter in our triplet activation story is again in collaboration with the Baik group at KAIST.

Welcome Matthew!

The Yoon lab is pleased to welcome its newest graduate student, Matthew Rossler!  

Benzylic Alkoxylation

BJ and Kimberly have developed a method for alkoxylation of benzylic C–H bonds with a range of alcohol nucleophiles, featuring very high site-selectivity and functional group compatibility. The method, first reported on ChemRxiv, has now been published in ACIE.

Triplet Rebound

Jian, Wes, Hoimin, Kaz, and Jesse have identified an unusual mechanism of enantioselective photoactivation in a JACS full paper. This study required synthetic and kinetic studies from our group, transient absorption spectroscopy in Jerry Meyer‘s group, and computations in Mookie Baik‘s group. What a team!

Enantioselective [2+2] Cinnamate Photocycloadditions

Mary Beth and BJ’s study of asymmetric cinnamate ester photocycloadditions appears in JACS. Part of a great collaboration with the Baik group at KAIST!

Photocatalytic Pyrrolidine Synthesis

We are pleased to contribute Adrian and Evan’s article on a Photocatalytic Strategy for Pyrrolidine Synthesis to the Asian JOC Special Issue on Heterocyclic Chemistry.

Counteranion Effects in Photoredox Catalysis

Elliot, Steven, and Wes have published a full paper in JACS analyzing the origins of a surprising counteranion effect in photocatalytic radical anion Diels–Alder cycloadditions. A paper six years in the making!

Cope Scholar Award

Tehshik is honored to be a recipient of a 2019 Cope Scholar Award — along with colleague Bob McMahon!

Photocatalytic Oxyamination

Nic, Maddie, and Vlad have published an Org Lett paper describing an approach to alkene oxyamination that uses unmodified nucleophilic carbamates as N-atom donors.
