Acid-promoted C1-C2 Bond Fission and Subsequent 1,5-Sulfenyl Shift of 1-Acceptor-1-sulfenyl-substituted 2-Vinylcyclopropanes. Formation of 6-Sulfenyl-α,β-γ,δ-unsaturated Carboxylic Esters and Nitriles

1-Acceptor-1-sulfenyl-substituted 2-vinylcyclopropanes were isomerized to 6-sulfenyl-α,β-γ,δ-unsaturated carboxylic esters and nitriles via a C₁-C₂ bond fission and via a 1,5-sulfenyl shift using an acid catalyst.
