Scope of the Suzuki−Miyaura Cross-Coupling Reaction of Potassium Trifluoroboratoketohomoenolates

Potassium trifluoroboratoketohomoenolates were prepared in good yields from either the corresponding α,β-unsaturated compounds or methyl ketones. These organoboron reagents were effectively cross-coupled with various aryl and heteroaryl chlorides.
