Reactions of α-halonitrosoalkanes with resorcinol

α-Halonitrosoalkanes react with resorcinol as nitrosylating agents to form 3-hydroxy-N-(2,4-dihydroxyphenyl)-1,4-quinone imine.

Photoreduction of 1,1,2-trichlorotrifluoroethane initiated by TiO2 particles

Reductive dehalogenation of 1,1,2-trichlorotrifluoroethane (CFC 113) takes place upon illumination of air-free suspensions of TiO2 particles containing formate ions. Chloride ions and 1,2-dichlorotrifluoroethane (HCFC 123a) are the main reaction products. Reaction rates increase with increasing concentration of CFC even beyond the solubility limit of the Freon in water. Evidence is presented that a chain transformation of the Freon takes place in formate solutions. The results are explained assuming that reduction of the Freon proceeds via a radical chain mechanism, which involves participation of CFC and formate species located on as well as next to the oxide surface.

Isomerization reaction of dichlorotrifluoroethane

The invention discloses an isomerization reaction of dichlorotrifluoroethane. The reaction uses 2,2-dichloro-1,1,1-trifluoroethane as a raw material, and 1,2-dichloro-1,1,2-trifluoroethane (R123a) and1,1-dichloro-1,2,2-Trifluoroethane (R123b) are prepared under the action of an isomerization catalyst, wherein the isomerization catalyst is a mixture of AlF3 and AlCl3. The reaction has the advantages of simple process, strong operability, low cost, and the like.

Selective reduction of halopolyfluorocarbons by organosilicon hydrides

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, and ClSi(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 much more reactive and reaction with hydrosilane rapidly proceeds without the catalyst at elevated temperature.
