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


Cut it out! Logan Bartholomew and Filippo's publication of a formal deletion of carbon to convert pyrimidines to pyrazoles is out in J. Am. Chem. Soc. pubs.acs.org/doi/10.1021/ja…


Congrats Taylor Bednar. Well deserved 👏🏿

Hi Friends! Applications are open for Merck’s Underrepresented Chemists of Color Research Award! Applications are due March 1. It’s a great opportunity to network with Merck scientists and present your research. Email [email protected] with any questions #ChemTwitter 🧑🏽🔬

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
