ABSTRACT:
Olefin Methathesis is accomplished by combining olefins with acetylenes and ungsten salts such as tungsten hexachloride. This process simplifies olefin metathesis as acetylenes can be handled in the atmosphere, while ethylaluminum dichloride or related materials which have been used in the past instantaneously ignite when exposed to the atmosphere. Furthermore, the acetylenes bring about the reaction with much greater speed than when the initiator is a combination of a metal carbene and an acetylene. Besides, double bonds introduced in the polymer are highly stereoselective.
