We report the transition metal-free decarboxylative cross-coupling reactions of acyl fluorides with potassium perfluorobenzoates. Compared with traditional transition metal-catalyzed cross-couplings, this protocol presents an extremely environmentally benign pathway to afford unsymmetrical diaryl ketones. To install perfluorophenyl groups, this method highlights highly selective, inexpensive, and nontoxic
RhH(PPh3)4 and 1,2-bis(diphenylphosphino)benzene (dppBz) catalyze the aryl exchange reaction of polyfluorinated diaryl sulfides. By employing these catalysts, unsymmetrical polyfluorinated diaryl sulfides are synthesized by the reaction of symmetrical polyfluorinated diaryl sulfides and substitutedpentafluorobenzenes in the presence of triisopropylsilane.
efficient and simple procedure was developed to synthesize substituted fluorinatednitriles and diarylketonesundermildconditions from polyfluorobenzenes and phenylacetonitriles. This coupling process was achieved by using a selectiveC–Fbondfunctionalization without a transition-metal catalyst. The reactions had good functional group tolerance and provided the products in moderate to excellent yields
