Technical Abstract: Increasing interest in commercial applications due to their physical properties and relatively straightforward synthesis. Herein, oleyl carbonate (1), an olechemical-based compound derived from oleyl alcohol, was epoxidized utilizing performic acid generated in situ from formic acid and 50% H2O2. The reaction proceeded smoothly and furnished the corresponding oleyl carbonate bisepoxide, (2, bis[8-(3-octyloxiran-2-yl)octyl] carbonate), in good yields (83-85% isolated yields after purification by silica gel chromatography). The carbonate moiety was found stable to the reaction conditions utilized for epoxidation and the isolated oleyl carbonate bisepoxide was subsequently characterized using Fourier transform infrared spectroscopy (FTIR), 1H and 13C nuclear magnetic resonance spectroscopy (NMR), and liquid chromatography electrospray ionization mass spectrometry (LC-ESI-MS). As epoxidized materials are important industrial materials, oleyl carbonate bisepoxide compound may be of potential interest as a plasticizer, monomer, or further chemical elaboration.
