| Abstract
| - It is demonstrated that silicon hydrides can be used for reduction of polyfluorinated halocarbons. For example, the reaction between CF3CCl2F and excess triethylsilane, catalyzed by benzoyl peroxide, leads to the formation of a mixture containing CF3CHClF (major), CF3CH2F, andClSi(C2H5)3. On the other hand, the reaction of chlorofluoroalkanes, containing an internal−CCl2− group readily proceeds with reduction of both chlorines, leading to compounds such as(CF3)2CH2 and CF3CH2C2F5. In contrast to chlorofluoroalkanes, bromofluoroalkanes are muchmore reactive and reaction with hydrosilane rapidly proceeds without the catalyst at elevatedtemperature.
