  Square-Planar Cu(II) Diketiminate Complexes in Lactide Polymerization

  摘要：

  Cu(OiPr)(2) was reacted with several beta-diketimine ligands, nacnac(R)H. Sterically undemanding ligands with N-benzyl substituents afforded the dimeric heteroleptic complexes [nacnac(Bn)Cu(mu-OiPr)](2) and [3-Cl-nacnac(Bn)Cu(mu-OiPr)](2) (Bn = benzyl). With sterically more demanding amines, dimerization was not possible, and the putative nacnacCuOiPr intermediate underwent ligand exchange to the homoleptic bisdiketiminate complexes Cu(nacnac(ipp))(2) and Cu(nacnac(Naph))(2) (ipp = 2-isopropylphenyl, Naph = 1-napthyl). Homoleptic complexes were also prepared with N-benzyl ligands to yield Cu(nacnac(Bn))(2) and Cu(3-succinimido-nacnac(Bn))(2). All complexes were characterized by single-crystal X-ray diffraction. Even bulkier ligands with N-anthrylmethyl, N-mesitylmethyl, or N-methylbenzyl substituents failed to react with Cu(OiPr)(2). In the case of nacnac(dipp)CuOiPr, putative nacnac(dipp)CuOiPr decomposed by beta-hydride elimination. Heteroleptic complexes [nacnac(Bn)Cu(mu-OiPr)](2) and [3-Cl-nacnac(Bn)Cu(mu-OiPr)](2) are very highly active rac-lactide polymerization catalysts, with complete monomer conversion at ambient temperature in solution in 0.5-5 min. In the presence of free alcohol, the homoleptic complexes seem to be in equilibrium with small amounts of the respective heteroleptic complex, which are sufficient to complete polymerization in less than 60 min at room temperature. All catalysts show high control of the polymerization with polydispersities of 1.1 and below. The obtained polymers were essentially atactic, with a slight heterotactic bias at ambient temperature and at -17 degrees C.

  Reaction of the lithium salts of N,N'-dialkyl-2-amino-4-imino-pent-2-enes, nacnac(R)Li(THF) (R = CH2Ph, Cy, nPr, iBu or S-CH(Me)Ph), with half an equivalent of CrCl2(THF)(x) yielded the homoleptic complexes (nacnac(R))(2)Cr. All complexes were characterized by X-ray diffraction studies and displayed a highly symmetric, square-planar coordination around the chromium center with strong boat-like distortions of the diketiminate ligands. Reaction of nacnacRLi(THF) (R = CH2Ph, Cy) with one equivalent of CrCl2(THF)(x) afforded the dimeric complexes nacnac(R)Cr(mu-Cl)}(2). (c) 2010 Elsevier B.V. All rights reserved.
