[figure: see text] Palladium-catalyzedarylation of the electron-rich olefin butyl vinyl ether has been accomplished in the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]), using as the arylating agents aryl iodides and bromides instead of the commonly used, but commercially unavailable and expensive, aryl triflates. The reaction proceeds with high efficiency and remarkable
Mechanistic studies concerning the use of 1,10-phenanthroline derivatives as palladium ligands in the Heck reaction are described. The work is focused on the steering factors for the coordination of unsaturated systems onto palladium(0) and palladium(II) complexes.
