α-palladation of Imines as entry to dehydrogenative heck reaction: Aerobic oxidative cyclization of N-Allylimines to Pyrroles
We report here a palladium(II)-catalyzed oxidative cyclization reaction of N-allylimines derived from methyl ketones, typically acetophenones, affording pyrrole derivatives at room temperature under oxygen atmosphere. The ...
Cobalt-catalyzed directed alkylation of arenes with primary and secondary alkyl halides
A cobalt–N-heterocyclic carbene catalyst allows ortho-alkylation of aromatic imines with unactivated primary and secondary alkyl chlorides and bromides under room-temperature conditions. The scope of the reaction encompasses ...
Cobalt-catalyzed ortho alkylation of aromatic imines with primary and secondary alkyl halides
We report here cobalt–N-heterocyclic carbene catalytic systems for the ortho alkylation of aromatic imines with alkyl chlorides and bromides, which allows the introduction of a variety of primary and secondary alkyl groups ...
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. ...
Cobalt-catalyzed chelation-assisted alkylation of arenes with primary and secondary alkyl halides
Cobalt–N-heterocyclic carbene catalytic systems have been developed for chelation-assisted ortho-alkylation of aromatic compounds with alkyl halides. Aryl imines can be selectively monoalkylated at room temperature by ...
