Abstract:By use of a half-sandwich scandium dialkyl complex bearing cyclopentadienyl ligand with a phosphine oxide side arm [(C5Me4SiMe 2CH2P(O)Ph2)Sc(CH2SiMe 3)2] in the presence of [Ph3C][B(C 6F5)4], the cyclocopolymerization of 1,6-heptadiene with styrene has been achieved for the first time to afford a new family of cyclopolyolefins containing a six-membered ring (methylene-1,3- cyclohexane), a five-membered ring (ethylene-1,2-cyclopentane), and styrene-styrene units.
