2-Benzoyloxy-F-propene, an F-enol ester, is shown to serve as a good and selective acceptor towards nucleophilic radicals generated from cyclic ethers, alcohols, and alkyl iodides to afford the addition product. The scope and synthetic utility of the radical addition reaction are described.

Synthesis and polymerization of novel fluorinated acrylates and methacrylates bearing alkoxyl groups derived from radical addition reaction of perfluoroisopropenyl ester
Radical addition of 2-benzoxypentafluoropropene [CF2C(CF3)OCOC6H5] (BPFP) with alcohols such as ethanol and 2-propanol was investigated to afford fluorinated alcohols. Radical addition of BPFP with cyclic ethers such as tetrahydrofuran, 1,3-dioxolane and tetrahydropyran was also achieved to afford addition products followed by hydrolysis to yield fluorinated alcohols possessing cyclic structures. Novel
研究了将2-苯并木五氟丙烯[CF 2 C(CF 3)OCOC 6 H 5 ](BPFP)与醇例如乙醇和2-丙醇自由基加成,得到氟化的醇。还实现了BPFP与环醚如四氢呋喃,1,3-二氧戊环和四氢吡喃的自由基加成以提供加成产物,随后水解以产生具有环状结构的氟化醇。由氟化醇与(甲基)丙烯酰氯合成了新型的丙烯酸氟代烷基酯和甲基丙烯酸氟代酯。(甲基)丙烯酸氟代烷基酯的自由基聚合反应产生的聚合物的最高分子量为1.2×10 5。
