  • Photocatalytic selective C(sp3)–H activation/cross-coupling reactions are appealing in organic synthesis. Here the authors describe the development of excited-state Pd-catalyzed dehydrogenative β-sulfonylation reactions using amines and aryl sulfonyl chlorides via intermolecular hydrogen atom transfer and C−S cross-coupling processes at room temperature.

  • Although the combination of photo- and nickel catalysis has garnered intense interest in the preceding years, the mechanisms by which these transformations occur are to some degree unresolved. Here the authors provide computational and spectroscopic support for a Dexter energy-transfer mechanism in the context of a C(sp3)–H alkylation.

  • Synthetic chemistry approaches for direct C–H bond alkylation offers a promising alternative to traditional functional-group-centered strategies which often involve multi-step procedures and may suffer from a variety of challenges including scalability. Here, the authors introduce resonant acoustic mixing as an efficient method for meta-C–H alkylation of arenes using a Ru-catalyst via a radical mechanism, avoiding the need for bulk solvents, external temperature, or light.

  • The selective construction of C-C double bonds in alkenes, which can be one of two isomers, is a fundamental focus of organic chemistry. Here, the authors systematically investigated the stereoselectivity in allylic C(sp3)-H bond arylations and demonstrated a ligand switch could allow a stereodivergent synthesis of silyl enol ethers.
