  • Photochromic and Reductive Electrochemical Switching of a Dithiazolylethene with Large Redox Modulation

    characterized. Due to the N‐methylation of the pyridyl rings, 2 a displays not only very different photochromic properties, but also undergoes a reductive ring‐closing reaction to generate its closed‐ring isomer 2 b. Careful electrochemical studies coupled with EPR spectroscopy show that this reductive ring‐closing reaction takes place when 2 a is two‐electron reduced. DFT calculations suggest that
    一个新的dipyridylthiazolylethene(1)和它的双阳离子类似物(2),具有两个N-甲基吡啶环,已被合成和结构表征。由于吡啶环的N-甲基化,2只不仅显示非常不同的光致变色特性,而且还经历还原性闭环反应,以生成其闭合环异构体2b中。仔细的电化学研究以及EPR光谱分析表明,这种还原性闭环反应是在2 a被两电子还原时发生的。DFT计算表明,这种基态电环化是由还原的闭环异构体2 b的非常大的稳定性驱动的相对于还原的开环异构体2 a。此外,2b在半波电势为0.04和-0.14 V时相对于SCE表现出两个连续且可逆的单电子降低,当从2 a传递到2 b时,实现了高达1 V的氧化还原调制。

    A catalyic process is disclosed for producing fluorine-substituted hydrocarbon products of the formulae RCH2CF2R and RFC═CHR at an elevated temperature, from compounds of the formula RCHFCHFR, where each R is independently selected from the group consisting of —CF3, —CF2CF3 and —CF2CF2CF3 or where both R groups of a formula together are —(CF2)2—, —(CF2)3— or —(CF2)4—. Suitable catalysts include carbon catalysts and catalysts containing at least one compound of a selected metal (e.g., Na, K, Rb, Cs, Y, La, Ce, Pr, Nd, Sm, Cr, Fe, Co, Rh, Ni, Cu, and/or Zn) supported on carbon. The saturated gem-dihydro- products may also be produced by hydrofluorinating the corresponding olefinic product over such catalysts at an elevated temperature, and can be combined with various other miscible solvents to form compositions useful for cleaning. Compounds such as CF3CF2CH2CF2CF3, CF3CF2CH2(CF2)2CF3, CF3CH═CF (CF2)2CF3, CF3CF═CH(CF2)2CF3, CF3CF2CH2(CF2)3CF3, CF3(CF2)2CH2(CF2)2CF3, CF3CH═CF(CF2)3CF3, CF3CF═CH (CF2)3CF3, CF3(CF2)2CH2(CF2)3CF3, CF3CF2CH2(CF2)4CF3, CF3CH═CF(CF2)4CF3, CF3CF═CH (CF2)4CF3, CF3CF2CH═CF(CF2)3CF3, CF3CF2CF═CH(CF2)3CF3 and and azeotropic compositions such as azeotropes of CF3CH2CF2CF2CF3 and/or CF3CF2CH2CF2CF3 with methanol, ethanol, or isopropanol are disclosed.
    本发明揭示了一种催化过程,用于在高温下从公式RCHFCHFR的化合物中制备公式RCH2CF2R和RFC═CHR的氟代烃产品,其中每个R独立地选自由群组成的—CF3,—CF2CF3和—CF2CF2CF3,或者公式的两个R组合在一起是—(CF2)2—,—(CF2)3—或—(CF2)4—。适当的催化剂包括碳催化剂和含有至少一种选择金属化合物(例如Na、K、Rb、Cs、Y、La、Ce、Pr、Nd、Sm、Cr、Fe、Co、Rh、Ni、Cu和/或Zn)的催化剂,该金属化合物支持在碳上。通过在这样的催化剂上在高温下进行氢氟化反应,也可以制备饱和的双氢基产品,并且可以与各种其他混溶溶剂结合以形成用于清洁的组合物。揭示了如CF3CF2CH2CF2CF3、CF3CF2CH2(CF2)2CF3、CF3CH═CF(CF2)2CF3、CF3CF═CH(CF2)2CF3、CF3CF2CH2(CF2)3CF3、CF3(CF2)2CH2(CF2)2CF3、CF3CH═CF(CF2)3CF3、CF3CF═CH(CF2)3CF3、CF3(CF2)2CH2(CF2)3CF3、CF3CF2CH2(CF2)4CF3、CF3CH═CF(CF2)4CF3、CF3CF═CH(CF2)4CF3、CF3CF2CH═CF(CF2)3CF3、CF3CF2CF═CH(CF2)3CF3和类似于CF3CH2CF2CF2CF3和/或CF3CF2CH2CF2CF3的共沸组成物与甲醇、乙醇或异丙醇的共沸物也被揭示。
