Allylic amination

Grace, Ellie, and Nic have leveraged an unexpected observation into an unusual method for allylic amination using Cu(II)-mediated radical–polar crossover.  Online now at OL!

Fe-mediated decarboxylative coupling

Grace and Sam’s magnum opus on Fe(III)-mediated photochemical couplings of carboxylic acid feedstocks is published in Chem. This is the second installment in a productive collaboration with Scott Bagley and Mark Bundesmann at Pfizer.

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 …

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, …
