Excited to share our latest work is now out on @J_A_C_S !!!! We report a visible-light-driven platform for alkyl radical generation from redox-inert substrates based on photo-active sulfur-intermediates formed via polar activation. doi.org/10.1021/jacs.6…

Our latest paper has been published in @ChemCommun ! “Synthesis of sulfur- and oxygen-bridged cationic [4]-helicenes mediated by Friedel–Crafts-SNAr tandem reactions for red-light-driven organophotoredox catalysis” @YutaGoto1557196 #OpenAccess pubs.rsc.org/en/content/art…

A new method from the @Shenvi_Lab enables the construction of branched molecular frameworks from simple alkenes via controlled MHAT chemistry, resolving a longstanding selectivity challenge and accelerating access to drug-relevant structures, as reported in @ScienceMagazine.
