We describe Cu-catalyzed intermolecular alkynylation and allylation of unactivated C(sp3)-H bonds with singly occupied molecular orbital-philes (SOMO-philes) via hydrogen atom transfer (HAT). Employing N-fluoro-sulfonamide as a HAT reagent, a set of subst

Visible-light-induced heterogeneous photocatalysis for decarboxylative alkynylation has been performed. The using of cheap, metal-free and recyclable graphitic carbon nitride (g-C3N4) as the photoredox catalyst in the process enables

C(sp3)-C(sp) bond formations are of immense interest in chemistry and material sciences. We report herein a convenient, radical-mediated and catalytic method for C(sp3)-C(sp) cross-coupling. Thus, with AgNO3 as the catalyst and K2S2O8 as the oxidant, various aliphatic carboxylic acids underwent decarboxylative alkynylation with commercially available ethynylbenziodoxolones in aqueous solution under mild conditions. This site-specific alkynylation is not only general and efficient but also functional group compatible. In addition, it exhibits remarkable chemo- and stereoselectivity.
