Resumen:
Fatty acid methyl esters (FAME) are usually obtained from the transesterification of natural oils and fats with a lower alcohol. Most of all oleochemistry reactions of FAME are carried out in the carboxy functions, but the synthesis of products formed by reactions of the C=C bonds is becoming increasingly important at industrial level. FAME metathesis has been studied in homogeneous catalysis using mainly Ru complexes, but very few papers have investigated the reaction on solid catalysts. Here, we studied the self-metathesis of methyl oleate (MO) on Hoveyda-Grubbs (HG) complexes and methyltrioxorhenium (MTO, CH3ReO3), both supported on commercial silica. The MO metathesis (Figure 1) yields 9-octadecene and 9-octadecene-1,18-dioate (9-OD), a valuable product used in polymer, fragrance, lubricant, and fine chemistry industries.
