A visible-light-promoted method for generating amidyl radicals from N-fluorosulfonamides via a manganese-catalyzed N-F bond activation strategy is reported. This protocol employs a simple manganese complex, Mn2(CO)10, as the precatalyst and a cheap silane, (MeO)3SiH, as both the hydrogen-atom donor and the F-atom acceptor, enabling intramolecular/intermolecular hydroaminations of alkenes, two-component carboamination of alkenes, and even three-component carboamination of alkenes. A wide range of valuable aliphatic sulfonamides can be readily prepared using these practical reactions.

A novel asymmetric 6-endo aminoacetoxylation of unactivated alkenes by palladium catalysis, which yields chiral β-acetoxylated piperidines with excellent chemo-, regio- and enantioselectivities under very mild reaction conditions, has been established herein by employing a new designed pyridine-oxazoline (Pyox) ligand. Importantly, introducing a sterically bulky group into the C-6 position of Pyox is crucial to enhance the reactivity of the aminoacetoxylation of alkenes.
Copper-Promoted Intramolecular Aminotrifluoromethylation of Alkenes with Langlois Reagent as the Trifluoromethyl Source

A novel approach for copper-promoted intramolecular aminotrifluoromethylation of alkenes using inexpensive CF3SO2Na as the trifluoromethyl source is described. The feature of this method is the concurrent construction of a five-membered ring and a C-CF3 bond in the simple copper salt/TBHP system. A gram-scale reaction was tested with a slight decrease in the yield. This protocol provides an operationally simple, step-economical and synthetically useful access to a variety of trifluoromethyl indolines, pyrrolidines and lactams.
