  Synthesis, structure and magnetic characterization of decamethylmetallocenium ethyl tricyanoethylenecarboxylate charge-transfer salts

  摘要：

  Ethyl tricyanoethylenecarboxylate (ETCE) is a one-electron acceptor related to tetracyanoethylene that can serve as a building block for the construction of molecule-based magnets. The reactions of ETCE with decamethylmetallocenes, MCp2* (M = Cr, Mn, Fe) give three new charge-transfer salt magnets, [CrCp2*][ETCE] 1, [MnCp2*][ETCE] 2 and [FeCp2*][ETCE] 3. The expected mixed pi stacking of anions and cations is obtained, with the ETCE radical anion exhibiting typical disorder over two nearly equivalent footprints. Powder diffraction supports the belief that all three compounds are isomorphous. Magnetic measurements indicate that 1 is a soft ferromagnet, ordering below a critical temperature, T-c, of 3.8 K. Compound 2 exhibits complex magnetic behavior consisting of two frequency-dependent peaks in the ac susceptibility, the first at about 11.2 K and the second at about 7 K. At 1.8 K, the compound is hysteretic and exhibits a coercive field of 10 kG. Compound 3 is a glassy, apparently canted, ferromagnet displaying an out-of-phase ac susceptibility signal below about 3 K. (C) 2008 Elsevier B. V. All rights reserved.

  用于环加成-逆电环化 (CA-RE) 和相关反应的酯取代的贫电子烯烃

  摘要：

  我们报告了由羧酸酯和氰基四取代的缺电子烯烃与富电子（二甲氨基）苯基取代的炔烃的反应。单酯或二酯取代的烯烃仅经历 [2+2] 环加成 - 逆电环化 (CA-RE) 反应，这对于多氰化乙烯来说已经很好建立，而三酯和四酯取代的烯烃也经历 [4+2] 杂-Diels –Alder (HDA) 反应与形成第三个产物，推测是通过 [3+2] 环加成反应，然后重排。电化学研究揭示了从 CA-RE 反应中获得的丁-1,3-二烯的第一还原电位的阴极位移，因为氰基取代了酯部分。通过酯交换、重氮化学对酯取代的 1,3-二烯进行后 CA-RE 功能化，并描述了交叉耦合。药理学上有趣的吡唑并吡喃的形成说明了酯取代的 CA-RE 产品的合成效用。

  Rhenium(I) enolate complexes Re(NCCHCO2Et)[NC(EtO2C)C=CHPh](PMe2Ph)4 and Re(NCCHCO2Et)(NCCH2CO2Et)(PMe2Ph)4 are found to catalyze unique olefin metathesis reaction of tetracyanoethylene with ethyl α-cyanocinnamate to give 1,1 dicyano-2-phenylethylene and ethyl 2,3,3-tricyanopropenoate at room temperature.

  We present the synthesis of a new high Curie temperature (Tc ∼ 145 K) organic-based magnet with composition V[ETCEC]1.3·0.3 CH2Cl2 formed by the reaction of ethyl tricyanoethylenecarboxylate (ETCEC) with V(CO)6 in CH2Cl2. Analysis of the IR spectrum indicates that all nitrile and carbonyl oxygen are coordinated to V(II) sites. Temperature-, field-, and frequency-dependent measurements of the magnetization

• Reversible Diels−Alder Reactions for the Generation of Dynamic Combinatorial Libraries

  日期：2005.1.1

  Condensation reactions between various dienes and dienophiles have been screened for reversibility. Functionalized fulvenes, bearing in particular biological groups, and cyanolefins have been found to react rapidly and reversibly, in the temperature range from -10 to +50 degreesC. These results pave the way for the development of dynamic combinatorial libraries based on reversible Diels-Alder chemistry.
