Rhodium‐Catalyzed Alkylation of C−H Bonds in Aromatic Amides with Non‐activated 1‐Alkenes: The Possible Generation of Carbene Intermediates from Alkenes
The alkylation of C−H bonds (hydroarylation) in aromatic amides with non‐activated 1‐alkenes using a rhodium catalyst and assisted by an 8‐aminoquinoline directing group is reported. The addition of a carboxylic acid is crucial for the success of this reaction. The results of deuterium‐labeling experiments indicate that one of deuterium atoms in the alkene is missing, suggesting that the reaction does
A Ni-catalyzed direct C–H alkylation of N-quinolylbenzamides using alkylsilyl peroxides as alkyl-radical precursors is described. The reaction forms a new C(sp3)–C(sp2) bond via the selective cleavage of both C(sp3)–C(sp3) and C(sp2)–H bonds. This transformation shows a high functional-group tolerance and, due to the structural diversity of alkylsilyl peroxides, a wide range of alkyl chains including
The Nickel(II)-Catalyzed Direct Benzylation, Allylation, Alkylation, and Methylation of C–H Bonds in Aromatic Amides Containing an 8-Aminoquinoline Moiety as the Directing Group
Direct alkylation via the cleavage of the ortho C–H bonds by a nickel-catalyzed reaction of aromaticamides containing an 8-aminoquinoline moiety as the directing group with alkyl halides is report...
