摘要:
A nickel/Lewis acid catalyzed intermolecular cycloaddition reaction of o-cyanobenzylarylketones with allcynes to form naphthalenones is developed. This reaction is promoted by the nickel/Lewis Acid catalyst pair and involves the cleavage of two C-C sigma bonds to eliminate arylcyanide and the formation of different two C-C sigma bonds with alkyne insertion.
