Resumen:
The activity and selectivity of silica-supported Hoveyda?Grubbs (HG) complex for the cross-metathesis of methyl oleate with 1-hexene to obtain 1-decene, methyl 9-tetradecenoate, 5-tetradecene and methyl 9- decenoate were studied in a batch reactor. TheHGcomplex loadingwasvaried between 0.87 and 11.6 wt%.Competitive secondary reactions were the self-metathesis of methyl oleate and the self-metathesis of 1-hexene. The yield to cross-metathesis products (C-M) was 47% when a 1-hexene/methyl oleate reactant ratio (RC6/MO) of one was employed. The C-M value increased with increasing 1-hexene initial concentration, reaching 87% for RC6/MO = 7. The selectivity to terminal olefins also increased at the expense ofinternal olefins among the cross-metathesis products when the concentration of 1-hexene was increased.
