Cobalt-catalyzed ortho-C-H alkylation of 2-arylpyridines via ring-opening of aziridines
A cobalt–N-heterocyclic carbene catalyst, in combination with neopentylmagnesium bromide, was found to promote ortho-C[BOND]H functionalization of 2-arylpyridines with 1,2-diarylaziridines through ring-opening alkylation. ...
Ortho-C–H Benzylation of Aryl Imines with Benzyl Phosphates under Cobalt–Pyphos Catalysis
Ortho-C–H benzylation of aryl ketimines with benzyl phosphates is achieved with the aid of a catalytic system consisting of a cobalt(II) salt, a phosphine/pyridine bidentate ligand, and a Grignard reagent under room-temperature ...
