Application of olefin metathesis in oleochemistry: an example of green chemistry

Rhenium heptoxide on alumina, promoted by a small amount of tetramethyltin, is an active and very selective catalyst for the heterogeneous metathesis of unsaturated fatty acid esters.

Heterogeneous metathesis of unsaturated fatty acid esters

Surface acidity of several metathesis catalysts, Re2O7/Al2O3, Mx Oy·Re2O7/Al2O3(Mx Oy= V2O5, MoO3 or WO3) and Re2O7/SiO2·Al2O3, have been studied in situ by Fourier transform infrared spectroscopy using pyridine adsorption. A distinct correlation has been found between the activity for metathesis and Bronsted acidity of the catalysts, while their Lewis acidity showed no correlation with the activity.

A model for the generation of active sites of rhenium-containing metathesis catalysts

Low-loading Re2O7/Al2O3·B2O3–MR4(M = Sn or Pb, R = alkyl) catalysts show high activity and selectivity at room temperature (293 ± 2 K) for the metathesis of functionalized alkenes; this is attributed to their strong Bronsted acidity.

Re2O7/Al2O3·B2O3 metathesis catalysts

The metathesis of linolenic and linolenic esters with tungsten hexachloride–tetramethyltin as catalyst yields a considerable amount of cyclohexa-1,4-diene (up to 30 mol % of the reaction mixture in the case of methyl linolenate) along with alkenes, and monocarboxylic and dicarboxylic esters.
