The (fulvalene)Ru2(CO)4 complex is the only known metal-based photoswitch capable of both harvesting solar energy upon irradiation and releasing it on demand, acting as a molecular solar–thermal fuel....

We present a photochemical reaction that enables the direct coupling of carboxylic acids with structurally diverse amines, alcohols, and arenes. This method takes advantage of the ready availability o...

Strategies for C–H amination with sulfonamides have been dominated by stoichiometric strategies or Rh/Cu catalysis using strong oxidants, elevated temperatures, or excess equivalents of C–H partner. We developed a photocatalytic C–H amination with a bench-stable N-methoxypyridinium salt that is amenable to late-stage functionalization efforts. We discovered a competitive proton-coupled electron transfer pathway between sulfonamide and a pyridine byproduct that inhibits the reaction. Catalysis was re-established with the introduction of ZnBr2.
