  Suzuki Coupling of 2‐Chloroacrylonitrile, Methyl 2‐Chloroacrylate, or 2‐Chloroprop‐1‐en‐3‐ol with Arylboronic Acids Catalyzed by a Palladium‐Tetraphosphine Complex

  摘要：

  The tetraphosphine all-cis-1,2,3,4-tetrakis(diphenylphosphinomethyl) cyclopentane (Tedicyp) in combination with [Pd(C3H5)Cl](2) affords an efficient catalyst of the coupling of 2-chloroacrylonitrile with arylboronic acids. In the presence of 1% catalyst, the 2-arylacrylonitrile derivatives were obtained in medium to good yields. A variety of substituents such as alkyl, methoxy, fluoro, trifluoromethyl, formyl, or nitro on the arylboronic acid are tolerated. The cross-coupling reactions of methyl 2-chloroacrylate with arylboronic acids give simple access to 2-phenylacrylate derivatives, which are useful precursors for the synthesis of biologically active compounds such as ibuprofen, ketoprofen, and naproxen.
