cycloadditions involving benzyne intermediates. The precursor offers an efficient alternative for generating benzynes compared to widely used ortho TMS triflates under similar reaction conditions. With the utilization of this new precursor, the formation of potentially genotoxic trifluoromethanesulfonate side product is eliminated. The applicability of the new benzyneprecursor was demonstrated in different

The insertion of fluorinated 1,3-dicarbonyl compounds to benzyne resulted in regioselective formation of various fluorinated 1,5-dicarbonyl compounds which are not readily available by other methods. Products include 2-trifluoroacetyl- and 2-(perfluoroalkanoyl)phenylacetic estres, 2-fluoro-2-phenylacetic esters, 1-aryl-2-(2-trifluoroacetylphenyl)ethan-1-ones and other derivatives.
