Cyclopentadienylsodium and phenylethynylsodium are effective cocatalysts with WCl<SUB>6</SUB> in the homogeneous olefin metathesis. The optimum mole ratios of C<SUB>5</SUB>H<SUB>5</SUB>Na and PhC≡CNa to WCl<SUB>6</SUB> ranged more widely—from 1.5 to 3.0 and from 1.5 to 2.5 respectively—than that of BuLi to WCl<SUB>6</SUB>. The formation of the Friedel-Crafts products was extremely small—such as 1—%, if the cocatalyst/WCl<SUB>6</SUB> ratio was about 2. The new catalyst systems were less poisoned by ether than the other catalyst systems and were hardly deactivated in the course of the reaction. The characteristics of these catalyst systems were discussed.
