The reaction of 3-methoxy-1-phenylthio-1-propene with aryl and primary alkyl Grignardreagents in the presence of nickel(II)–phosphine complexes in benzene or toluene proceeded chemo- and regioselectively to give 1-alkenyl phenyl sulfides in high yields.

aminoalkoxides, leading to new superbases, induced an efficient one-pot dialkylation of allylphenylsulfide. The regioselectivity of the reaction (α,α′ vs α,γ) was found as strongly dependent on the nature of the alkyl halide. As an application, α,γ dialkylated products were efficiently converted into the corresponding unsymmetrical ketones.
