If you haven’t already, apply to participate in the Pfizer Inc. Chemistry Connect symposium. I participated two years ago and I truly enjoyed it. Applications are due tomorrow, Oct. 5th, so don’t wait! I’m looking forward to hearing some awesome talks 😁#PfizerChemOutreach #NOBCChE

Frustrated you got the wrong diastereomer? In Science Magazine this week WendlandtLab show a photocatalyst and HAT co-catalyst can epimerize tertiary stereocenters in a wide variety of complex molecules science.org/doi/10.1126/sc…

Ever wanted to read an entire Chemical Reviews over a single cup* of coffee? Well, you’re in luck! A 2.5-page ChemRev (!) highlighting exciting recent advances in asymmetric catalysis of radical chemistry: pubs.acs.org/doi/full/10.10… * … or however else you consume @Twitter these days

Our latest is a project that exemplifies the deceptive "quick project" - it turns out that trapping radicals generated from primary amines and our anomeric amide reagent is not as straightforward as it looks, and we learned a lot in the process! 🧵 pubs.acs.org/doi/10.1021/ja…

Replace an aromatic carbon with nitrogen, leave the rest of the skeleton the same. A huge first step towards the problem I started my lab to tackle, thanks to Tyler Pearson, Ryoma Shimazumi, Julia Driscoll 🇵🇸, Balu Dherange, and Dong-Il. science.org/doi/full/10.11…

Are you #team_abstraction or #team_substitution to break C-Cl bonds? Check out work by Samir, Imma, and Blaise in Angewandte Chemie on an electrocatalytic system that can switch between these mechanisms to functionalize unactivated chloroalkanes. tinyurl.com/mr4yf55y
