Novel amphiphilic fluoroalkylated derivatives of xylitol, D-glucose and D-galactose for medical applications: Hemocompatibility and co-emulsifying properties

1-O-(4,4,5,5,6,6,7,7,8,8,9,9,9-Tridecafluorononyl)xylitol 6 was synthesized as a novel standard compound for the assessment of hemocompatibility and co-emulsifying properties in microemulsions for biomedical uses. 3-O-(1,1,2,4,4,5,7,7,8,8,9,9,9-Tridecafluoro-5-trifluoro-methyl-3,6- dioxanonyl)-D-glucose 9 and 6-O-(1,1,2,4,4,5,7,7,8,8,9,9,9-tridecafluoro-5-trifluoromethyl-3,6- dioxanonyl)-D-galactose 12 were synthesized by nucleophilic addition of protected carbohydrates to perfluorinated vinyl oligoether. Biological tests revealed very good hemocompatibility and co-emulsifying properties for the amphiphiles 6, 9 and 12.

Perfluoro tertiary alcohols. III. (Perfluoroalkyl)- and (perfluorooxaalkyl)-trimethylsilanes in the synthesis of perfluorinated tertiary alcohols

High-molecular weight perfluorinated tertiary alcohols, Rf1,Rf2,Rf3C(OH) f1=n-C8F17, Rf2=CF3, Rf3=n-C6F13; Rf1=(CF3)2CFO(CF2)4, Rf2=CF3, Rf3=n-C6F13; Rf1=C3F7O2CF(CF3), Rf2=CF3, Rf3=n-C6F13; Rf1=n-C8F17, Rf2=CF3O2(CF2)2, Rf3=(CF3)2CFO(CF2)2> (IIIa-d), have been prepared by the reactions of (perfluoroalkyl)- and (perfluorooxaalkyl)-trimethylsilanes (Ia-d) with fluoroketones (IIa-c).Ketones containing a trifluoromethyl group as well as higher molecular weight perfluorinated substituents have been studied under different experimental conditions.The yield of tertiary alcohol is influenced by the solvents, reaction temperatures, type and concentration of metal fluorides, and structures of the fluoroalkyltrimethylsilanes and fluoroketones.The reaction has been extended to carbonyl compounds other than ketones.While a perfluorinated secondary acid fluoride gave good yield of the ketone, no reaction was observed with esters.

DIPHOSPHATETRAAZACYCLOOCTATETRAENES. II. PROPERTIES AND DEGRADATIONS

1,5-Bis(diphenylphospha)-3,7-bis(perfluoroalkylether)-2,4,6,8-tetraazacyclooctatetraene and 1,3-bis(diphenylphospha)-5,7-bis(perfluoroalkylether)-2,4,6,8-tetraazacyclooctatetraene were found to decompose at 316 deg C to phospha-s-triazines.The symmetrical arrangement liberated perfluoroalkylether nitrile with concommitant formation of the corresponding diphospha-s-triazine; the unsymmetrical isomer eliminated the (C6H5)2PN unit to give the monophospha-s-triazine.The thermal and oxidative stabilities of the two compounds differed widely with the unsymmetrical isomer being significantly more stable than the symmetrical arrangement.Spectral data pertinent to these results are discussed.Both materials were found to be effective in arresting perfluoroalkylether fluid degradation in oxidizing atmospheres in the presence of metal alloys.
