Chemical transformation of perfluoroalkyl iodoalkanes
The oligomerization method was developed by the British ICI company [44~45], with recycled ptfe powder tetrafluoroethylene anion CF, =CF, one (CF.),

Based on polymerization, prepare long carbon chain fluoroalkane tetramer:
CEGE-based intermediate is also a kind of preparation fluorine-containing
Surfactant method. Tetrafluoroethyl rocr, GA, pentamer: alkene, hexafluoropropylene and the corresponding epoxidized CBSB compound (such as hexafluoropropylene oxide) under the catalysis of fluorine KC-ion, and aprotic polar EC~CF, Anionic polymerization anti-hexamer can occur in Cu Fao solvents:
Should produce Cg~Cic perfluorooligomeric ECS KECCE products. The oligomerization product of tetrafluoroethylene is EGEFCE
Among them, pentamers account for about 65% of the entire mixture. Since the fluorine atom on the carbon atom of the double bond is easily replaced by a nucleophile, the desired linking group can be introduced through this reaction.
