Abstract
The metathesis of methyl oleate with the WCl6-cocatalyst system was investigated. Tetra-n-butyl-stannane, tetraethylstannane and triethylaluminum were effective as cocatalysts. The optimum reaction condition was considerably different from that for the metathesis of internal alkene having no functional group. The addition of methyl oleate or methyl stearate depressed the various side reactions in the metathesis of alkenes having no functional group. These facts indicate that in spite of the high reaction temperature, the relatively high selectivity is obtained in the metathesis of methyl oleate owing to the existence of its ester group. Cross metathesis of methyl oleate and 1-decene was examined.
