• 物理描述：
  Dichlorodifluoroethylene is a liquid material, which may cause illness from inhalation. When heated to high temperatures it may decompose and emit toxic fumes. When in contact with water or steam it may produce additional fumes that can cause illness from inhalation. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams.

  Pentafluorophenyl-lithium has been treated with a number of halogeno-olefins of the type CXYCFZ (X, Y, Z, being F, Cl, Br or H). When the olefins were CF2CFCl and CF2CCl2 the products isolated were C6F5CFCFCl and C6F5CFCCl2 together with derivatives formed by nucleophilic attack of C6F5Li on the polyfluoroaryl ring. The orientation of this attack was shown by chemical and spectroscopic methods to be

  五氟苯基锂已用多种CXY CFZ类型的卤代烯烃（X，Y，Z为F，Cl，Br或H）处理过。当烯烃为CF 2 CFCl和CF 2 CCl 2时，分离的产物为C 6 F 5 CF CFCl和C 6 F 5 CF CCl 2以及通过C 6 F 5 Li亲核攻击多氟芳基环而形成的衍生物。化学和光谱学方法表明这种攻击的方向在4位。但是，如果烯烃为CFCl，CFCl或CF 2形成CHCl，氯五氟苯基乙炔。当CF 2 CFH或CF 2 CFBr是烯烃C 6 F 5 C CC 6 F 5时，会分离出其进一步的五氟苯基取代的衍生物，例如C 6 F 5– C 6 F 4 C CC 6 F 5。已经提出了一种机制来解释这些结果。还描述了溶剂和卤化锂对反应过程的影响。

  The addition of thiols to chlorofluoroethylenes was carried out under γ-ray irradiation; chlorofluoroethyl alkyl sulfides were thus obtained. Ghlorofluoroethyl alkyl sulfoxides and sulfones were prepared by the oxidation of the sulfides. The dehydrohalogenation of chlorofluoroethyl alkyl sulfides yielded chlorofluorovinyl alkyl sulfides, whose structure indicated that the thiyl radical attacked the

  The reactions of SF5OCl and SF5OF with fluorinated ethylenes were used to prepare new SF5O- substituted fluorocarbons in 44–77% yield. Compounds prepared were SF5OCF2CFHCl, SF5OCFClCF2Cl, and the isomeric mixture SF5OCFBrCF2Cl/SF5OCF2CFBrCl. Spectroscopic and other characterizing data for the adducts are presented. Numerous attempts to prepare SF5OCF=CF2 by dehalogenation of the dichloro or bromochloro
