Preparation of a stable trifluoroborate salt for the synthesis of 1-aryl-2,2-difluoro-enolethers and/or 2,2-difluoro-1-aryl-ketones via palladium-mediated cross-coupling.
A bench-stable potassium trifluoroborate enol ether reagent has been prepared. This reagent is suitable for the incorporation of 2,2-difluoroenolethers into aryl and heteroaryl systems via palladium-mediated cross-coupling with suitable halide coupling partners.
