1.52 g Aliquat 100 (tetrabutyl ammonium bromide, TBAB) and 8.3 mg Pd(OAc)2 were placed in a 5 mL vial with crimp cap. This mixture was heated to 120° C. under vacuum for 2.5 hours. The vial was put under N2-atmosphere and 312 mg (1 mmol) methyl ricinoleate was added. This mixture was heated to 120° C. for 94 hours. The product was extracted from the TBAB with heptane. After concentration 172 mg was obtained. The reaction products were analyzed by GC (FIG. 11): 8 area % methyl ricinoleic acid methyl ester, 15 area % at 2.54′, 21 area % at 11.8′, 20 area % at 12.77′ and 33 area % at 13.69′. No 12-oxostearate methyl ester was formed.
