• Selective Reduction of Halopolyfluorocarbons by Organosilicon Hydrides
  作者：Viacheslav A. Petrov

  DOI：10.1021/jo9807363

  日期：1998.10.1

  It is demonstrated that silicon hydrides can be used for reduction of polyfluorinated halocarbons. For example, the reaction between CF(3)CCl(2)F and excess triethylsilane, catalyzed by benzoyl peroxide, leads to the formation of a mixture containing CF(3)CHClF (major), CF(3)CH(2)F, and ClSi(C(2)H(5))(3). On the other hand, the reaction of chlorofluoroalkanes, containing an internal -CCl(2)- group

  已证明氢化硅可用于还原多氟化卤代烃。例如，CF（3）CCl（2）F和过量的三乙基硅烷之间的反应（由过氧化苯甲酰催化）导致形成包含CF（3）CHClF（主要），CF（3）CH（2）F的混合物，和ClSi（C（2）H（5））（3）。另一方面，包含内部-CCl（2）-基团的氯氟烷烃的反应很容易同时还原两个氯，从而导致化合物如（CF（3））（2）CH（2）和CF（3） CH（2）C（2）F（5）。与氯氟烷烃相比，溴氟烷烃具有更高的反应活性，在没有催化剂的情况下，与氢硅烷的反应迅速进行，且温度较高。

  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。
