Perfluorooctanoic acid (PFOA) or perfluorooctane sulphonate (PFOS) was one of the most prominent fluorosurfactants and applied widely in firefighting and daily chemical,etc. However, these surfactants have recently been identified as toxic and undegradability in the environment. Developing an efficient approach to environment-friendly fluorosurfactants is essential. A fluorocarbon branched chain strategy was adopted to develop /PFOS substitutes. A series of intermediates of novel branched fluorinated surfactants with CF3CF2CF2C(CF3)2group were synthesized from perfluoro-2-methyl-2-pentene. All the steps were mild, easy-handled and cheap. It is expected to be a very significant direction for the development of non-bioaccumulable alternatives of PFOA or PFOS.
