Abstract:
Cross-metathesis of unsaturated fatty acid esters such as natural oils, fats or their
derivatives is a useful method to convert renewable natural resources into valuable chemical
products in oleochemical industry. In this work, methyl oleate has been used as a
representative of the most common unsaturated methyl ester and cross metathesized with
various types of monomers such as diallyl amine, vinyl caprolactam, vinyl carbazole in the
presence of ruthenium-based catalyst (Second generation Grubbs catalyst,
RuCl2(PCy3)(H2IMes)(CHPh)). The reaction was taken under an inert atmosphere in a onepot
system. The effects of reaction temperatures, reaction times, catalyst loadings and
monomer to methyl oleate molar ratios on the selectivity of the cross metathesized products
have been discussed. The results showed the strong donating ability of the monomer
containing electron donating group or lone pair electrons closed to carbon-carbon double
bond to the catalyst which can cause catalyst deactivation and led to low methyl oleate
conversions with no selectivity on metathesis products. However, the monomers containing
aromatic rings in which electrons can be localized within the molecules such as vinyl
carbazole showed 59% conversion with 30% selectivity of cross metathesis products. The
appropriate reaction condition was catalyst/methyl oleate molar ratio of 0.05, vinyl
carbazole/methyl oleate molar ratio of 5 equivalents at 65 °C for 3 h in dichloromethane.
