Synthesis of Diverse Aromatic Ketones through C-F Cleavage of Trifluoromethyl Group.

An efficient synthetic method of aromatic ketones through C-F cleavage of trifluoromethyl group is disclosed. The high functional group tolerance of the transformation and the remarkable stability of trifluoromethyl group in various reactions enabled multisubstituted aromatic ketone synthesis in an efficient route involving useful transformations such as ortho -lithiation, aryne chemistry, and cross-couplings.
