Nickel-Catalyzed Conversion of Enol Triflates into Alkenyl Halides.

Julie L Hofstra1, Kelsey E Poremba1, Alex M Shimozono1, Sarah E Reisman1.   

Abstract

A Ni-catalyzed halogenation of enol triflates was developed and it enables the synthesis of a broad range of alkenyl iodides, bromides, and chlorides under mild reaction conditions. The reaction utilizes inexpensive, bench-stable Ni(OAc)2 ⋅4 H2 O as a precatalyst and proceeds at room temperature in the presence of sub-stoichiometric Zn and either 1,5-cyclooctadiene or 4-(N,N-dimethylamino)pyridine.
