Ritter-type C−H aminationAmidesAlkylarenesNitrilesCerium photocatalysisReported here is a photocatalytic strategy for Ritter‐type CH amination of alkylarenes with nitriles. Under the irradiation of blue light and the catalysis of a simple Ce(III) salt, alkylarenes were brominated by CBr 3 COOH...
The Ritter-type amination of a tertiary C-H bond using iodic acid (HIO 3 ) as an oxidant, in the presence of N-hydroxyphthalimide (NHPI) is reported. This operationally simple method is conducted under metal-free conditions, is scalable, and efficiently provides valuable α-tertiary amine deri...
C—H Amination of unactivated sp3 centers (non-benzylic and non-allylic) using MeCN as an inexpensive source of nitrogen proceeds under scalable and mild conditions and high functional group tolerance in the presence of a modified Selectfluor reagent.doi:10.1002/chin.201233041...
