omega-dichloroperfluoroalkanes, the similarly stepwise reactions with an alkene is not clean, both bis-adducts and the corresponding omega-hydrides, RCH(2)CH(2)(CF(2))(n)()H as byproducts are also formed. In the absence of alkenes or alkynes, per- and polyfluoroalkyl chlorides can be converted to their sulfinate salts and sulfonyl chlorides.

(EN) Nonaqueous pharmaceutical compositions for use in aqueous physiological systems are disclosed comprising drug delivery vehicles suspended in nonaqueous perfluorocarbon or fluorinated silicone liquid carriers. The suspended drug delivery vehicles may be water labile or water stable and incorporate therapeutic or diagnostic compounds which remain stable and pharmaceutically effective for extended periods. The pharmaceutical compositions possess extended shelf-lives and do not leach the incorporated therapeutic or diagnostic compounds into the liquid carriers making them well suited for multi-dose packaging and administration.(FR) Compositions pharmaceutiques non aqueuses utilisées dans des systèmes physiologiques aqueux comprenant des véhicules de libération de médicaments en suspension dans des supports liquides de perfluorocarbone ou de silicone fluorée non aqueux. Les véhicules de libération de médicaments en suspension peuvent être labiles dans l'eau ou stables dans l'eau et ils comprennent des composés thérapeutiques ou diagnostiques demeurant stables et pharmaceutiquement efficaces pendant des durées prolongées. Les compositions pharmaceutiques ont des durées de conservation prolongées et elles ne font pas peser par lixiviation dans les supports liquides les composés thérapeutiques ou diagnostiques incorporés, ce qui les rend bien adaptées à un conditionnement et une administration de doses multiples.

An organ to be transplanted, such as a kidney, can effectively be preserved for an increased period of time by perfusion using a perfusate which is made of a Ringer's solution modified by increasing its potassium ion content to 8-20 meq/liter with a stably emulsified perfluorocarbon compound and dissolved albumin. A preferred concentration of the perfluorocarbon compound, for example perfluorodecalin, is 7.5 to 12.5%(W/V) and that of albumin is 1-8%(W/V) based on the perfusate.

Perfluorocarbon liquids are disclosed as being useful as substitutes for the vitreous or aqueous of the eye, and as transparentizing agents in the cornea or lens of the eye. Radiopaque liquid perfluorocarbons are useful as radiopaque agents in diagnostic procedures on the eye.
Gas transport agents containing a perfluorocyclocarbon and an amine oxide are disclosed. These compositions provide emulsions or solutions for use in oxygen transport, particularly in animals. They are therefore useful as artificial blood compositions. Large concentrations of perfluorocarbons may be employed even up to 50% or more by volume in preparing emulsions, microemulsions or solutions. The emulsions or solutions are stable under room temperature storage conditions
