• Alkylfluorenyl substituted N-heterocyclic carbenes in copper(<scp>i</scp>) catalysed hydrosilylation of aldehydes and ketones

  Copper(I) complexes featuring N-heterocyclic carbenes (NHCs) in which the nitrogen atoms are substituted by a 9-ethyl-9-fluorenyl group (EF) have been synthesised and tested in the hydrosylilation of functionalized and/or sterically demanding ketones and aldehydes. These reactions, carried out with triethylsilane as hydride source, were best achieved with the imidazolylidene copper complex 2d in which

  合成并测试了N-杂环卡宾（NHC）（其中的氮​​原子被9-乙基-9-芴基（EF）取代）的铜（I）配合物，并在官能化和/或空间需求的酮的加氢水解反应中进行了测试。醛。用三乙基硅烷作为氢化物源进行的这些反应最好用咪唑基亚烷基铜络合物2d来完成其中EF取代基可以围绕相应的N–CEF键自由旋转。活性物种的出色稳定性超过了先前报道的Cu–NHC催化剂的稳定性，这可能取决于NHC侧臂在催化循环过程中通过形成夹心状中间体来保护铜中心的能力，还取决于其空间柔性，便于采用承压物。吨数达到1000。
• A Simple and Efficient Copper-Catalyzed Procedure for the Hydrosilylation of Hindered and Functionalized Ketones

  The catalytic hydrosilylation of highly hindered and functionalized ketones is described. The combination of inexpensive catalyst precursors, CuCl and NHC-HX (NHC = N-heterocyclic carbene), leads to a highly efficient reduction mediator for the preparation of silyl ethers from unfunctionalized and functionalized alkyl, cyclic, bicyclic, aromatic, and heteroaromatic ketones. A series of catalyst precursors have been structurally characterized and a catalyst-structure activity relationship is discussed.

  The synthesis of novel copper (1) N-heterocyclic carbene complexes is described. Thus, reaction of CuX with 1,3-di(2-propyl)3,4,5,6-tetrahydropyrimidin-2-ylidene yields CuX(1,3-di(2-propyl)-3,4,5,6-tetrahydropyrimidin-2-ylidene) (X=Cl, (1a), Br (1b)); however, reaction of CuCl with 1,3-dimesityl-3,4,5,6-tetrahydropyrimidin-2-ylidene yields the bis-N-heterocylcic carbene complex Cu(1,3-dimesityl-3,4,5,6-tetrahydropyrimidin-2-ylidene)(2)(+) CuBr2-(2). A supported version of 1, i.e. PS-DVB-CH2-OCO-CF2-CF2-CF2-COOCu(1,3-di(2-propyl)-3,4,5,6-tetrahydropyrimidin-2-ylidene) (3) was prepared from I and PS-DVB-CH2-OCO-CF2-CF2-CF2-COOAg. A copper loading of 4.15 mu mol/g was realized. The new compounds were used as catalysts in carbonyl hydrosilylation and cyanosilylation reactions. Excellent reactivity was observed, giving raise to turn-over numbers (TONs) of up to 100,000. Compounds 1a, 1b, and 2 have also been used as catalysts for the atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA). A linear conversion of monomer with time was observed, however, no control over molecular weight of PMMA was observed. (c) 2005 Elsevier Ltd. All rights reserved.
