Cyclic alternating ring-opening metathesis polymerization (CAROMP). Rapid access to functionalized cyclic polymers

摘要

Catalysis of alternating ROMP with (H_2IMes)Cl _2Ru-CHPh(OiPr), the second generation Hoveyda-Grubbs catalyst, provided an entirely cyclic alternating polymer. Conditions for the cyclic AROMP were used to prepare a polymer in which one of the repeat units bore a primary alkyl chloride that was used for further elaboration.
