制备方法与用途

生产方法 

在500mL圆底烧瓶中加入76g(1mol)硫氰酸铵和158g(0.5mol)Ba(OH)2·8H2O,摇荡直到固体液化。将溶液加热到不再有NH3气放出,间歇补充已蒸发的水。此时混合物应对酚酞呈碱性反应。必要时可以多加些Ba(OH)2并重复上述过程。这时溶液中往往会有白色至灰黑色的沉淀物。用磨砂布氏漏斗过滤。在滤液中加入12mol/L硫酸到溶液对石蕊仅呈微碱性。剩余的Ba(OH)2用CO2中和。煮沸溶液以除去可能生成的Ba(HCO3)2。用磨砂布氏漏斗过滤,将滤液加热至沸,加入05g活性炭,再一次过滤。最后的滤液浓缩到沸点升高至125℃(不得超过)。先冷至室温,再在冰浴中冷却。将生成的三水合物晶体收集在布氏漏斗中,在空气中干燥。产量115g,产率75%。加热到160℃失水。

    名称:
    Catalysis of Anilide Ethanolysis by Barium− and Strontium−Ethoxide Pairs and Their Complexes with 18-Crown-6
    摘要:
    The metal-bound ethoxide species that are quantitatively formed upon mixing equimolar amounts of Me4NOEt and alkaline-earth (Ba, Sr) metal salt in ethanol solution are more reactive than free ethoxide in the cleavage of simple activated amides (e.g. N-methyl-2,2,2-trifluoroacetanilide) lacking any donor group for binding to the metal ion. It is suggested that a metal-coordinated solvent molecule acts as a general acid catalyst for expulsion of the aniline leaving group in the ratel determining step. The position of the proton in the transition state is strongly dependent upon structural variations in the aniline portion, as suggested by the magnitude of kinetic solvent isotope effects. Enhanced catalysis is observed upon addition of equimolar amounts of 18-crown-6, which is tentatively interpreted on the basis of the notion that ion pairing is weakened upon cation binding to a crown ether. Important differences concerning metal ion effects in amide vs ester cleavage are pointed out and discussed on the basis of results obtained upon structural modifications of the substrates.

    experimentally and computationally. ILs based on these anions and imidazolium and pyrrolidinium cations, some of which are functionalised with hydroxyl and nitrile groups, have been examined. IL-anion coordination has been investigated and compared to typical weakly coordinating anions. We have found there is potential for competition at the Cu-centre and cases of anions traditionally assigned as weakly associating

    Quinones of Benzo- and Dibenzo-Crown Ethers: The preparation of the 1,4-quinones of benzo[15]crown-5 (1), benzo [18]crown-6 (2) and dibenzo[18]crown-6 (3) and their quinols is described. The quinones are obtained by Fremy salt oxidation of the corresponding 3-hydroxybenzo-crown ethers which are readily accessible by a double protective group synthesis from 1,2,3-trihydroxybenzene. The synthetic pathway also provides a general high yield preparation of 2,3-dialkoxyl-1,4-benzoquinones. The new crown ethers are characterised b y 1H- and 13C-N. M. R. as well as U. V. spectroscopy. Non-aqueous redox potentials are determined by cyclic voltammetry. Crystalline complexes of 1 and 2 with various ammonium, alkali, and alkaline earth cations are also described.
