Efficient Aryl–(Hetero)Aryl Coupling by Activation of CCl and CF Bonds Using Nickel Complexes of Air‐Stable Phosphine Oxides

Abstract

A couple of couplings: Air-stable diamino- and dioxophosphine oxides are used as preligands in the nickel-catalyzed Kumada cross-coupling reactions of aryl Grignard reagents. A sterically hindered preligand allows for highly efficient cross-coupling of aryl fluorides at ambient temperature (acac=acetylacetonate).
