Vinyl acetate was once mainly prepared by hydroesterification, i.e., the addition of acetic acid to acetylene in the presence of metal catalysts. Using mercury(II) catalysts, vinyl acetate was first prepared by Fritz Klatte in 1912. [3] Presently, zinc acetate is used as the catalyst: Y.-F. Han; D. Kumar; C. Sivadinarayana & D. W. Goodman (2004). "Kinetics of Ethylene Combustion in the Synthesis of Vinyl Acetate over a Pd/SiO 2 Catalyst" (PDF). Journal of Catalysis. 224: 60–68. doi: 10.1016/j.jcat.2004.02.028. Vinyl organometallics, e.g. vinyllithium and vinyl tributyltin, participate in vinylations including coupling reactions such as in Negishi coupling. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

If activated by an adjacent group, the increased polarization of the bond gives rise to characteristic reactivity, which is termed vinylogous:

The radical was first reported by Henri Victor Regnault in 1835 and initially named aldehydène. Due to the incorrect measurement of the atomic mass of carbon it was believed to be C 4H 6 at the time. Then in 1839 it was renamed by Justus von Liebig to " acetyl", because he believed it to be the radical of the acetic acid. [4]

In allyl compounds, where the next carbon is saturated but substituted once, allylic rearrangement and related reactions are observed. This method has replaced the addition of acetic acid to acetylene. The main side reaction is the combustion of organic precursors. Will show some signs that it was played and otherwise handled by a previous owner who took good care of it.Yasushi Obora; Yasutaka Ishii (2012).

Isotope labeling and kinetics experiments suggest that the mechanism involves PdCH 2CH 2OAc-containing intermediates. Beta-hydride elimination would generate vinyl acetate and a palladium hydride, which would be oxidized to give hydroxide.
