catalytic amount of CsF in DMF in good yields. The palladium-catalyzedcarbonylative cross-coupling reaction of 2 with aryl iodides bearing various functional groups smoothly proceeded giving the corresponding aryl 1-fluorovinyl ketones in good yields under an atmospheric pressure of carbon monoxide. A similar carbonylative cross-coupling reaction of 2 with aryl triflates was also accomplished in the presence
This invention relates to a range of 1-aryl-4-cyclopropylpyrazoles in which there is at least one fluorine attached to the cyclopropyl ring, to compositions comprising such compounds, processes to their synthesis and their use as parasiticides.
