Abstract Methyl 17-hydroxy stearate was converted to methyl octadec-16-enoate using copper sulfate adsorbed on silica gel. This compound served as a useful substrate for the olefin metathesis reaction. As a result, several fatty acids with novel functional groups at the ω-end were prepared: a glyceryl ether attached at the 18-carbon, an aromatic fatty acid from eugenol, and a ferrocenyl fatty acid. By employing the unsaturated fatty alcohol, other ...
