  Single-Site β-Diiminate Zinc Catalysts for the Alternating Copolymerization of CO₂ and Epoxides:  Catalyst Synthesis and Unprecedented Polymerization Activity

  摘要：

  Synthetic routes to zinc ss -diiminate complexes are reported. The synthesis of 11 ss -diimine [(BDI)H] ligands, with varying N-aryl substituents and bridging structures, is described. These ligands are converted to (BDI)ZnX complexes (X = OAc. Et. N(SiMe3)(2), Br, Cl, OH, OMe, (OPr)-Pr-i). X-ray structural data revealed that all zinc complexes examined exist as mu -X-bridged dimers in the solid state, with the exception of the zinc ethyl and amido complexes which were monomeric. Complexes of the form (BDI)ZnOR (R = alkyl, acyl) and (BDI)ZnN(SiMe3)(2) are highly active catalysts for the alternating copolymerization of epoxides and CO2. Copolymerizations of cyclohexene oxide (CHO) and CO2 with (BDI-1)ZnX [(BDI-1) = 2-((2,6-diisopropylphenyl)amido)-4-((2,6-diisopropylphenyl)imino)-2-pentene)] and (BDI-2)ZnX [(BDI-2) = 2-((2,6-diethylphenyl)amido)-4-((2,6-diethylphenyl)imino)-2-pentene)], where X = OAc, Et, N(SiMe3)(2), Br, Cl, OH, OMe, (OPr)-Pr-i, were attempted at 50 degreesC and 100 Psi CO2. Complexes with X = OAc, N(SiMe3)(2), OMe, (OPr)-Pr-i all produced polycarbonate by the alternated insertion of CHO and CO2 with similar catalytic activities, comparable molecular weights, and narrow molecular weight distributions (MWD similar to 1.1), indicating the copolymerizations are living. Furthermore, ligand effects were shown to dramatically influence the polymerization activity as minor steric changes accelerated or terminated the polymerization activity.

• Base Metal Catalysts for Photochemical C–H Borylation That Utilize Metal–Metal Cooperativity
  作者：Thomas J. Mazzacano、Neal P. Mankad

  DOI：10.1021/ja408861p

  日期：2013.11.20

  Heterobimetallic Cu-Fe and Zn-Fe complexes catalyze C-H borylation, a transformation that previously required noble metal catalysts. The optimal catalyst, (IPr)Cu-FeCp(CO)(2), exhibits efficient activity at 5 mol% loading under photochemical conditions, shows only minimal decrease in activity upon reuse, and is able to catalyze borylation of a variety of arene substrates. Stoichiometric reactivity studies are consistent with a proposed mechanism that exploits metal-metal cooperativity and showcases bimetallic versions of the classical organometallic processes, oxidative addition and reductive elimination.
