CAS 675-09-2: Mesitene lactone

4,6-Dimethyl-2-pyrone is a hydrogenated aromatic compound that is hydrophobic and has a tannin structure. The compound can be found in plants such as the leaves of the oak tree, where it occurs in small quantities. Tannins are used by plants to protect their cells from damage caused by ultraviolet radiation. 4,6-Dimethyl-2-pyrone is also found in ligands such as organocuprates, which are organic compounds that bind metals such as copper and chromium. It is formed by equilibration of hexadecanoic acid with 2-hydroxyacetophenone via an aluminium chloride catalyst. This reaction mechanism has been shown to be effective at temperatures below 160°C and at pressures of less than 1 bar. 4,6-Dimethyl-2-pyrone can also react with n-hexane to produce 6,6'-dimethylbiphenylsulfonium chloride (
