Abstract

[reaction: see text] Organocopper compounds prepared by the transmetalation of functionalized arylmagnesium halides with CuCN.2LiCl undergo smooth cross-coupling reactions with aryl fluorides and tosylates bearing a carbonyl function in the ortho position in the presence of Co(acac)(2) (7.5 mol %), Bu(4)NI (1 equiv), and 4-fluorostyrene (20 mol %) as promoters in DME/THF/DMPU leading to polyfunctional aromatics or heterocycles.
