  Zirconium and hafnium amide, alkoxide, and pyrrolyl complexes manifesting with pyrrolyl-linked N-donor ligands: Syntheses, characterization, and ring opening polymerization of ε-caprolactone

  摘要：

  A series of zirconium and hafnium alkoxide and amide complexes containing symmetrical tridentate pyrrolyl ligand, [C4H2NH(2,5-CH2NMe2)(2)] have been synthesized conveniently by treatment of 2,6-di-tert-butylphenol, tert-butanol or pyrrole in pentane and their reactivity over ring opening polymerization of epsilon-caprolactone have been carried out. Reactions of [C4H2NH(2,5-CH2NMe2)(2)] with M(NEt2)(4) (M = Zr or Hf) originate [C4H2N(2,5-CH2NMe2)(2)]M(NEt2)(3) (1, M = Zr; 2, M = Hf). Furthermore, reactions of [C4H2N(2,5-CH2NMe2)(2)]M(NEt2)(3) with 2,6-di-tert-butylphenol, tert-butanol or pyrrole afford [C4H2N(2,5-CH2NMe2)(2)]M(OC6H3-2,6-Bu-t(2))(NEt2)(2) (3, M = Zr; 4, M = Hf), [C4H2N(2,5-CH2NMe2)(2)]M((OBu)-Bu-t)(3) (5, M = Zr; 6, M = Hf) and [C4H2N(2,5-CH2NMe2)(2)]M(C4H4N)(3) (7, M = Zr; 8, M = Hf), respectively, in satisfactory yield. All the complexes have been characterized by NMR spectra as well 3, 4 and 6 subjected to the X-ray diffraction analysis. Complexes 3-8 have been used as initiators for the ring-opening polymerization of epsilon-caprolactone and observed broad PDI values (1.84-2.75) representing multiple reactivity centers of these complexes.
