Abstract
An organosilane having attached to the silicon at least one halogenated hydrocarbon radical containing at least one chlorine, bromine and/or iodine attached to an aliphatic group, any remaining valencies of the silicon being satisfied with monovalent hydrocarbon radicals or halogen atoms, is reacted with (a) hydrogen fluoride in the presence of a catalytic amount of antimony pentachloride, or (b) antimony fluoride in the presence or absence of the antimony pentachloride catalyst, whereby at least one of the halogens in the aliphatic group is replaced by fluorine. The halogenated hydrocarbon radical may be halo-alkyl, -alkenyl, -cycloalkyl and -cycloalkenyl, and aralkyl and alkaryl groups containing the halogen on the aliphatic portions thereof. Some of the halogen in the silane may be fluorine. The reaction may proceed spontaneously or may require heat and may be effected at any pressure. In the example (1) CCl3CH2CHBrSi(CH3)Cl2 was added to a mixture of SbF3 and SbCl5 to give the compounds CF3CH2CHBrSi(CH3)F2 and CF2Cl CH2CHBrSi(CH3)F2; (2) trichloromethylphenyltrichlorosilane, prepared by chlorinating tolyltrichlorosilane under ultra-violet light, is added to SbF3 to give trifluoromethylphenyltrifluorosilane (F3C.C6H4.SiF3); (3) the compound CF3.CF2.CH2.CHBrSi(C6H5) Cl2 is obtained from CBr3.CBr2.CH2.CHBrSi (C6H5) Cl2 and SbF3; (4) and (5) mixtures of isomers of the formula CF3.C6H4.SiF3 are obtained by bubbling hydrogen fluoride through a mixture of isomers of the formula CCl3.C6H4.SiCl3 and SbCl5. Specification 769,499 is referred to.
