Abstract
A method is provided for producing a specific crosscoupling compound and a specific catalyst for producing the compound. The method includes reacting in the presence of a base and a nickel compound catalyst organic halide of the formula n'(RX), wherein Ris a hydrocarbon group and the α and β carbons to X′ are spcarbon atoms; Xis a chlorine, bromine, or iodine atoms, and n and nand 1 or 2 but not both 2, with a compound having the formula m{R(BX)} where an Ris an aryl, heteroaryl, or alkenyl group, and n′ is 1 or 2, Xis independently a hydroxyl group, an alkoxy or arylalkoxy group or Xtogether form an alkylenedioxy or arylenedioxy group, and m represents 1 or 2 but m≦n, and the boron atom is bonded to a spcarbon atom of Rgroup or a boronic acid trimer anhydride.
