Photochemical C-H Amination of Ethers and Geminal Difunctionalization Reactions in One Pot.

A mild, atom-economic, and metal-free alpha-C-H amination of ethers using relatively stable nonafluorobutanesulfonyl (nonaflyl, Nf) azide as the aminating reagent to give N-sulfonyl hemiaminals is reported. This enables unprecedented C(sp(3)) difunctionalization reactions, leading to diverse functionalized amino group containing compounds starting from simple ethers in one pot.
