An improved process for the metathesis of alkenyl esters utilizing substantially reduced catalyst levels is provided. For the process, an alkenyl ester of the formula ##STR1## where R is hydrogen or alkyl, R* is tertiary alkyl or an aromatic group, and n is an integer from 2 to 20 is reacted with a tungsten hexachloride/tetraalkyltin catalyst.
