Abstract

A mild, atom-economic, and metal-free α-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(sp3 ) difunctionalization reactions, leading to diverse functionalized amino group containing compounds starting from simple ethers in one pot.
