A practical method for the palladium‐catalyzed ortho‐olefination of benzyl and phenethyl 2‐pyridyl sulfones with electron‐deficient alkenes using N‐fluoro‐2,4,6‐trimethylpyridinium triflate ([F+]) as the terminal oxidant is described. The chelating auxiliary (2‐pyridyl)sulfonyl unit was demonstrated to be the key to the success of this reaction, which occurs efficiently with excellent regioselectivity

Oxidative kinetic resolution of heterocyclic sulfoxides with a porphyrin-inspired manganese complex by hydrogen peroxide
reported here the low loading porphyrin-inspired high-valent manganese (IV)-oxo complex was applied in oxidative kineticresolution (OKR) of racemic heterocyclic sulfoxides using the environmentally benign hydrogen peroxide for the first time. This approach allows for rapid OKR (0.5 h) of a variety of racemic sulfoxides (including pyridine, pyrimidine, pyrazine, thiazole, benzothiazole, thiophene) in

cross-coupling reactions is described. Introducing electron-withdrawing groups on the aryl ring of the sulfone facilitates the Pd-catalyzed activation of C–SO2 bonds. Cross-coupling reactions with fluorinated sulfone electrophiles are reported, leading to a variety of multiply arylated products in good yields. The reactivity of this unusual electrophile is benchmarked versus common electrophiles and its use in
