M. Mitani et al., STEREOSELECTIVE CYCLOPOLYMERIZATION OF 1,5-HEXADIENE USING NOVEL BIS(FERROCENYL)ZIRCONOCENE CATALYST, Chemistry Letters, (10), 1995, pp. 905-906
A novel heterotrinuclear zirconium-iron complex 1 was synthesized and
crystal structure of 1 was determined by X-ray diffraction method, The
complex 1 efficiently catalyzed cyclopolymerization of 1,5-hexadiene
in the coexistence of methylaluminoxane to afford trans-poly(methylene
-1,3-cyclopentane) with high stereoselectivity (98% trans).
