Synthesis of [18F]Arenes via the Copper-Mediated [18F]Fluorination of Boronic Acids
A copper-mediated radiofluorination of aryl- and vinylboronic acids with K(18)F is described. This method exhibits high functional group tolerance and is effective for the radiofluorination of a range of electron-deficient, -neutral, and -rich aryl-, heteroaryl-, and vinylboronic acids. This method has been applied to the synthesis of [(18)F]FPEB, a PET radiotracer for quantifying metabotropic ...
