Heptafluoro-2-iodopropane, i-C3F7I, is a very efficient chain-transfer agent in telomerization reactions with 1, 1-difluoroethylene and tetrafluoroethylene; other telomerization reactions of CF3I, C2F5I and n-C3F7I with 1, 1-difluoroethylene and of n-C3F7I with tetrafluoroethylene are reported and the relative efficiencies of the iodides as chain-transfer agents are discussed. The telomer iodides have been coverted to useful models for some ...
