- HC CH CH3CO2H H,SO, H3C-C-O-C=CH2 H HgSO, Acetylene Acetic Acid Vinyl acetate Acetylene reacts with acetic acid in the presence of H,SO4 and HgSO4 to yield vinyl acetate, a monomer used in the production of poly(vinyl acetate). The reaction mechanism includes the following steps: 1. Formation of a bridged mercurinium ion intermediate between Hg- and acetylene; 2. Addition of acetic acid to open the three-membered ring; 3. Proton transfer to solvent to give an organomercury vinyl ester3; 4. Addition of H to the alkene to form a carbocation; 2+ 5. Expulsion of Hg²+ to form the alkene.
