In the presence of a thiyl radical species, catalytic Markovnikov thiol–ene reaction is challenging because it prefers to proceed via pathway, thereby leading anti-Markovnikov selectivity. this work, rare example engaged in enabled by cobalt catalysis reported. This protocol features avoidance unique oxidants, exclusive regioselectivity, and broad substrate scope. Scalable synthesis late-stage modification complex molecules demonstrate practicability protocol.

The construction of three-component supramolecular organic frameworks (SOFs) remains a challenge in this field due to the complex noncovalent interactions involved and limitations existing preparation methods. In study, we designed synthesized two photosensitive modules, with naphthalene-modified triphenylamine derivative (NA-TPA) as donor unit methylated-viologen-modified benzothiadiazole (DPBT) acceptor unit, which can self-assemble into two-dimensional framework (SOF) through encapsulation-enhanced donor–acceptor interaction cucurbit[8]uril (CB[8]) water. SOF not only nanosheet morphology water but also exhibit excellent luminescence enhancement performance. Compared monomers NA-TPA DPBT, effectively promote electron transfer greatly improve ability produce superoxide anion radicals (O2•–), be used photocatalyze thiol–ene cross-coupling reaction yield up 90%. This work provides useful exploration for SOFs photocatalytic application.

A Markovnikov-selective radical hydrochalcogenation reaction of unactivated alkenes via iron-catalyzed hydrogen atom transfer was reported. Using N-(arylsulfenyl)arenesulfonamide, PhSO2SCD3, S-alkyl thiosulfonate, dithiosulfonate and Ebselen derivatives as versatile radicalophiles, a wide range unsymmetrical alkyl-aryl, dialkyl SCD3 (D > 99%) containing sulfides, disulfides, well organoselenides have been collectively synthesized under mild conditions. As powerful alternative to the classical thiol–ene reaction, this protocol features exclusive Markovnikov selectivity, good functional group tolerance broad substrate scope. number probe experiments suggest proceeds through pathway. The synthetic utility transformation also demonstrated late-stage modifications diverse natural products bioactive molecules.
