In @science.org for chemsky this week, Phil Baran’s group apply sulfonylhydrazides to stereoretentive alkyl-alkyl coupling www.science.org/doi/10.1126/...

Stereoretentive radical-based alkyl-alkyl cross-coupling
The construction of stereogenic C(sp3)–C(sp3) bonds through cross-coupling remains a formidable challenge owing to competing β-hydride elimination and homocoupling as well as the poor inherent stereoc...

Temperature scanning reaction calorimetry allowed us gather a near-continuous set of rate constants (thousands !!) for our redox-neutral radical cross-coupling reactions. Then with our new mechanistic insights, we kinetically matched hydrazides with (Het)ArX to boost rxn yields up to 7x!

guys being a postdoc is so cool. I have spent my entire life wanting to be an academic and this has really locked it in for me. self doubt inherent in any competitive field aside, this is genuinely the most fun and exciting and interesting job I’ve ever had
