Abstract

Irradiation of perfluoroalkyl iodides RCF2I [R = C5F11, C7F15, C9F19,FO2SC2F4(CF2)5, Cl(CF2)5] with UV in the presence of Et3N and O2 afforded a simple and effective synthesis of perfluorocarboxylic acids RCO2H in 76-90% yields. The conditions used were mild and no hydrogen abstraction product was formed. The mechanisms of such photooxidn. was briefly discussed.

Key words: CARBOXYLIC ACID, REACTION MECHANISM, PHOTOOXIDATION, IODOHYDROCARBON, PERFLUORO-HYDROCARBON, PERFLUORO-HYDROCARBON

CLC Number:
