  • Kinetics and Mechanism of Acid Catalysed Hydration of α-Methylstyrenes
    作者:Oldřich Pytela、Bronislav Trlida
    DOI:10.1135/cccc20071025
    日期:——

    Twelve para-substituted α-methylstyrenes with substituents H, CH3, CF3, CH3O, CH3S, F, Cl, Br, CH3CO, CH3SO2, CN a NO2 were synthesised; additionally, the acid catalysed hydration kinetics of these compounds were measured in sulfuric acid in a concentration range c from 0.017 to 9.58 mol l-1, at 25.0 °C. The observed rate constants obtained were used to construct the kinetic acidity function and calculate the catalytic rate constants. Based on the evaluation of the acidity function kinetic dependence on acid medium concentration, and the substituent effects of acid catalysed hydration of α-methylstyrenes on the catalytic rate constants, the mechanism of acid catalysed hydration was verified. The mechanism involves the addition of a proton to the double bond of α-methylstyrene in the rate-limiting reaction step denoted as A-SE2. No evident difference was found between the effects of the acid medium on the acid catalysed hydration of styrenes and α-methylstyrenes, which indicates very similar activity coefficients of the reactants, and of the transition state of both substrates. The substituent effects evaluation shows that the rate-limiting step of the reaction consists in the addition of a proton to the substrate. The carbocation formation in the transition state of this reaction step proceeds roughly half-way compared with the extent of the carbocation formation by cumyl chloride hydrolysis. The obtained carbocation is in particular stabilised by the substituents with +M effect, while the influence of the substituents with -M and I effects is significantly smaller.

    十二种带有取代基H、CH3、CF3、CH3O、CH3S、F、Cl、Br、CH3CO、CH3SO2、CN和NO2的α-甲基苯乙烯被合成;此外,在浓度范围从0.017到9.58摩尔/升的硫酸中,测量了这些化合物的酸催化水合动力学。所得到的观察速率常数被用来构建动力学酸度函数并计算催化速率常数。通过评估酸性函数动力学对酸性介质浓度的依赖性,以及α-甲基苯乙烯的酸催化水合反应的取代基效应对催化速率常数的影响,验证了酸催化水合的机理。该机理涉及在速率限制的反应步骤中向α-甲基苯乙烯的双键加入质子,被标记为A-SE2。在酸性介质对苯乙烯和α-甲基苯乙烯的酸催化水合的影响之间没有明显差异,这表明反应物和两种底物的过渡态的活性系数非常相似。取代基效应评估显示,反应的速率限制步骤在向底物加入质子时发生。与叔丁基氯化物水解形成的碳正离子相比,该反应步骤的过渡态中的碳正离子形成大致进行了一半。所得到的碳正离子特别受到具有+M效应的取代基的稳定作用,而具有-M和I效应的取代基的影响则明显较小。
  • Asymmetric Hydrogenation of α,β-Unsaturated Nitriles with Base-Activated Iridium N,P Ligand Complexes
    作者:Marc-André Müller、Andreas Pfaltz
    DOI:10.1002/anie.201402053
    日期:2014.8.11
    Although many chiral catalysts are known that allow highly enantioselective hydrogenation of a wide range of olefins, no suitable catalysts for the asymmetric hydrogenation of α,βunsaturated nitriles have been reported so far. We have found that Ir N,P ligand complexes, which under normal conditions do not show any reactivity towards α,βunsaturated nitriles, become highly active catalysts upon addition
    尽管已知许多手性催化剂可以对多种烯烃进行高度对映选择性氢化,但迄今为止,尚未见有合适的催化剂可用于α,β-不饱和腈的不对称氢化。我们发现,在正常条件下对N,N-二异丙基乙胺加成的Ir N,P配位体络合物在对α,β-不饱和腈没有反应性的情况下变成高活性催化剂。碱活化的催化剂可以使H,2的α,β-不饱和腈共轭还原在低催化剂负载量下,可获得具有高转化率和出色对映选择性的相应饱和腈。相反,缺乏共轭氰基的烯烃在这些条件下不会发生反应,因此可以选择性还原α,β-不饱和腈的共轭CC键,而分子中其他类型的CC键则完好无损。 。

  • Highly Enantioselective Nickel-Catalyzed Hydrocyanation of Disubstituted Methylenecyclopropanes Enabled by TADDOL-based Diphosphite Ligands
    作者:Rongrong Yu、Xianjie Fang
    DOI:10.1021/acs.orglett.9b04374
    日期:2020.1.17
    A vast range of novel TADDOL-based diphosphite ligands were first synthesized and applied in the nickel-catalyzed asymmetric hydrocyanation of disubstituted methylenecyclopropanes. By employing these new catalysts, the conversion of diverse methylenecyclopropanes into their corresponding allylic nitriles was first enabled, in good yield with excellent enantioselectivities.

  • 1-Methyl-1-vinyl- and 1-Methyl-1-(prop-2-enyl)silacyclobutane: Reagents for Palladium-Catalyzed Cross-Coupling Reactions of Aryl Halides
    作者:Scott E. Denmark、Zhigang Wang
    DOI:10.1055/s-2000-6292
    日期:——
    1-Methyl-1-vinylsilacyclobutane (1) and 1-methyl-1-(prop-2-enyl)silacyclobutane (2) undergo rapid and high yielding cross-coupling with aromatic halides. Many different substituents and patterns on the aromatic moiety are tolerated. All reactions can be run at room temperature and require the presence of tetrabutylammonium fluoride and Pd(dba)2. Both silacyclobutanes can be made in one step from commercially available precursors.
