Nickel-Catalyzed Reductive Cyclization of Alkyl Dihalides
摘要:
The reductive coupling protocol to intra-molecular cyclization of dihaloalkanes is presented. It leads to five- and six-membered rings, with the former being more efficient. The incorporation of secondary alkyl halides generally promotes coupling, efficiency. To the best of our know ledge this is the first catalytic ring closure reaction arising form dihaloalkanes under chemical reductive conditions.
