Abstract

An alkyl-alkyl cross-coupling of organoboranes, formed in situ via hydroboration of alkenes, and Katritzky alkylpyridinium salts has been developed. Under the mild reaction conditions, a broad range of functional groups, including protic groups, is tolerated. The strategy is also effective with alkynes, enabling a C(sp3)-C(sp2) cross-coupling.
