A process for preparing a perfluoroalkyl-substituted compound comprises reacting a halopolyfluoroalkane having 1 to 20 carbon atoms with (1) a substituted or unsubstituted ethylene, (2) a substituted or unsubstituted acetylene or (3) a substituted or unsubstituted allylsilane, in the presence of a carbonyl complex of a Group VIII metal. Alternatively, the reaction (3) is effected under radial generating conditions. |
