title: Regioselective one-step synthesis of 4-fluoroalkylated isoquinolines via carbopalladation reaction of fluorine-containing alkynes.
abstract: [reaction: see text] The palladium-catalyzed annulation reaction of fluoroalkylated alkynes with various 2-iodobenzylidenamines was investigated. In the presence of a catalytic amount of Pd(PPh3)4, the reaction took place smoothly to give the corresponding 4-fluoroalkylated isoquinoline in high yield as a single isomer. No other regioisomer was detected.
