oxytrifluoromethylation of N-tethered alkenyl alcohols was developed providing straightforward access to CF3-containing morpholines derivatives. The method features mild reaction conditions with direct anodic oxidation of Langlois reagent as a cheap and easy to handle trifluoromethylating reagent. Variously substituted 2-(2,2,2-trifluoroethyl)morpholines were obtained in moderate to high yields under constant

A redox‐neutral intermolecular dicarbofunctionalization of styrenes with CO2 at atmospheric pressure and carbon‐centered radicals is described. This mild protocol results in multiple C−C bond‐forming reactions from simple precursors in the absence of stoichiometric reductants, thus exploiting a previously unrecognized opportunity that complements existing catalytic carboxylation events.
