Metathesis polymerization of 7-oxa-2,3-bismethoxycarbonylbicyclo[2.2.1]hepta-2,5-diene: synthesis of novel conjugated polyenes

Abstract
Novel high-molecular-weight polymers are readily made by the alkene metathesis reaction using 7-oxa-2,3-bismethoxycarbonylbicyclo[2.2.1]hepta-2,5-diene as the monomer and Ru and Os chlorides as catalysts; these polymers are readily dehydrogenated using dichlorodicyanobenzoquinone to afford novel purple–red conjugated polyenes.
