ABSTRACT:
A process for preparing a perfluoroalkyl-substituted compound is disclosed. The process comprises reacting a halopolyfluoroalkane having 1 to 20 carbon atoms with a compound selected from the group consisting of (1) a substituted or unsubstituted ethylene, (2) a substituted or unsubstituted acetylene and (3) a substituted or unsubstituted allylsilane, in the presence of a metal-carbonyl complex of the metal of the Group VIII of the Periodic Table. Alternatively, the reaction between the halopolyfluoroalkane and the substituted or unsubstituted allylsilane is effected under radical generating condition.
