Ligand-Free, Quinoline N-Assisted Copper-Catalyzed Nitrene Transfer Reaction to Synthesize 8-Quinolylsulfimides
An efficient copper-catalyzed, quinolyl N-directed nitrene transfer reaction to 8-quinolylsulfides was described. A variety of 8-quinolylsulfimides with different functional groups were synthesized in moderate to high yields. The obtained 8-quinolylsulfimides were proved to be promising novel type of bidentate ligands in Pd(II)-catalyzed allylic alkylation.
Cobalt (II) complexes of porphyrins are effective catalysts for intramolecular nitrene insertion of C—H bonds with arylsulfonyl azides. The cobalt-catalyzed process can proceed efficiently under mild and neutral conditions in low catalyst loading without

Cobalt-catalyzed intramolecular C-H amination with arylsulfonyl azides
(Chemical Equation Presented) Cobalt complexes of porphyrins are effective catalysts for intramolecular C-H amination with arylsulfonyl azides. The cobalt-catalyzed process can proceed efficiently under mild and neutral conditions in low catalyst loading
