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

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