New Perfluoroalkylated Phosphorus Amphiphiles

Phospholipids are the main components of biological membranes and the) spontaneously tend to self-assembly into liposomes. Synthetic double-chain so as bol amphiphiles allow the preparation of vesicles and can bc used as models of natural membranes and for preparing drug delivery systems. The formation of vesicles from single-chain perfluomalkylated phosphate or phosphoramidate amphiphiles war recently reported.1 We present the synthesis of new fluoroalkylatcd phosphinic acid amphiphiles bearing a P-C bond and an ionic polar head promoting self-organisation We have already described the synthesis of the phosphine derivatives by one-poireaction from red phosphorus via the in situ generation of PH3, and terminal alkenes and alkynes in basic media under sonication.2 We extend this reaction to perfluoroalkena under phase uansfert catalysis.
