Multiple Olefin Metathesis Polymerization That Combines All Three Olefin Metathesis Transformations: Ring-Opening, Ring-Closing, and Cross Metathesis

We demonstrated tandem ring-opening/ring-closing metathesis (RO/RCM) polymerization of monomers containing two cyclopentene moieties and postmodification via insertion polymerization. In this system, well-defined polymers were efficiently formed by tandem cascade RO/RCM reaction pathway. Furthermore, these polymers could be transformed to new A,B-alternating copolymers via a sequential cross metathesis reaction with a diacrylate. Additionally, we demonstrated the concept of multiple olefin metathesis polymerization in which the dicyclopentene and diacrylate monomers underwent all three olefin metathesis transformations (ring-opening, ring-closing, and cross metathesis) in one shot to produce A,B-alternating copolymer.

ETHER FORMATION FROM ALLYLIC ALCOHOLS CATALYZED BY SAMARIUM TRICHLORIDE

The behaviour of various allylic alcohols in the presence of catalytic amounts of SmCl3 (by heating in 1,2-dichloroethane) has been studied.Diallyl ethers are obtained in many cases in good yields.Mixed allyl alkyl ethers are also prepared if 2-5 equivalents of an aliphatic alcohol is present.The reactions are interpreted as proceeding through a pseudo allylic carbonium intermediate initiated by a preliminary complexation of the allyl hydroxyl to the samarium ion.
