This month has a lot of transitions for the group. We welcome Alana, Matthieu, and Max as new first-years in the group, and GM as a new undergraduate researcher. We also bid fond farewells to …
Year: 2022
TA spectroscopy for photocatalytic synthesis
TA spectroscopy can provide detailed insight into the mechanisms of photocatalytic reactions. Read Wes’ tutorial review in this year’s Specialist Periodical Reports – Photochemistry.
Cross-ketonization
Andrew developed a method to selectively combine two different carboxylic acid feedstocks into unsymmetrical ketones using a metallaphotoredox strategy. The result is a modern take on the industrial process of acid ketonization, updated for complex …
Uncontrolled Sensitization in Asymmetric Photocatalysis
Steven worked with Zeb Girvin (Miller group), Laura Cotter and Hyung Yoon (Mayer group) in a fun three-lab collaborative project on asymmetric [2+2] photocycloadditions of acyclic vinylpyiridines, now up at JACS. The reaction involves an …
LED-NMR + RPKA
LED-NMR is a data-rich analytical tool that is suitable for modern RPKA techniques. In studing an enantioselective photocatalytic reaction, Wes and Steven found that LED-NMR RPKA enabled determination of rate laws in a fraction of …
Cooperative Photocatalytic Stereocontrol
In the process of developing an enantioselective [2+2] photocycloaddition of vinylpyridines, Steven and Wes discovered stereochemical cooperativity between a chiral Brønsted acid catalyst and a chiral Ir photocatalyst. It’s a gratifying demonstration that matched/mismatched effects …
Cu-mediated Decarboxylative Coupling
The Yoon lab’s first publication of 2022 is a new oxidative decarboxylative coupling process based on the intrinsic photochemistry of Cu(II) carboxylate complexes. Check out the paper in Nature Chemistry. Congratulations Yukki, Sam, Grace, Kimberly, …
