                                    The palladium(0)-catalyzed condensation of aryl halides with the sodium salts of phenylsulfonylacetonitrile and diethyl cyanomethylphonate in dimethoxyethane gave the corresponding α-phenylsulfonylareneacetonitriles and diethyl arylcyanomethylphosphonates in good yields.The α-phenylsulfonylareneacetonitriles were easily desulfonylated with zinc to give the areneacetonitriles, and the arylcyanomethylphonates were converted to the alkylideneareneacetonitriles by means of the Horner-Emmons reaction.
