  Redox Control of Group 4 Metal Ring-Opening Polymerization Activity toward l-Lactide and ε-Caprolactone

  摘要：

  The activity of several group 4 metal alkoxide complexes supported by ferrocene-based ligands was controlled using redox reagents during the ring-opening polymerization of L-lactide and e-caprolactone. Switching in situ between the oxidized and reduced forms of a metal complex resulted in a change in the corresponding rate of polymerization. Opposite behavior was observed for each monomer used. One-pot copolymerization of the two monomers to give block copolymers was also achieved.

  摘要：

  1,1-二氨基二茂铁与一系列水杨醛的缩合导致以高产率形成相应的 salen 型配体。这些化合物作为配体的能力通过形成几种 1 → 1 Zr 和 Ti 配合物得到了证明，其中一种配合物进行了结构表征，并发现其具有方形平面构象的 t-BuSalfen2™ 配体。此外，通过二氨基二茂铁与2,4-戊二酮缩合合成了相关的席夫碱配体，并分离了该配体的Zr配合物。

  characterized tetrahedral cobalt salen (salen = N,N′-ethylenesalicylimine) complex was synthesized by using a 1,1′-ferrocene derivative, salfen (salfen = 1,1′- di(2,4-di-tert-butyl-6-salicylimine)ferrocene). The complex undergoes two oxidation events at low potentials, which were assigned as ligand centered by comparison to the corresponding zinc complex. The cobalt complex was found to catalyze the

  Schiff base metal complexes were investigated, where each series was supported by an ancillary ligand incorporating a ferrocene backbone and different N=X functionalities. One ligand is based on an imine, while the other is based on an iminophosphorane group. Cerium(IV), cerium(III), and yttrium(III) alkoxide complexes supported by the two ligands were synthesized. All metal complexes were characterized

  A rare example of a cerium(IV) alkoxide catalyst for lactide polymerization is reported. The lactide polymerization activity of the new cerium(IV) complex supported by a ferrocene Schiff base ligand, salfen, is compared to the activity of the yttrium analogue and to that of Ce(OtBu)4(THF)2. The complex Ce(salfen)(OtBu)2 is less active than Ce(OtBu)4(THF)2 and the corresponding yttrium(III) alkoxide

This isomerization was also observed in the presence of l-lactide (LA) before its ring-opening polymerization could occur. The isolation of a (salfen)Zr(OnPr)2 lactide intermediate supports the change to the trans coordination geometry necessary
