Synthesis and Surface Activity Study of a Novel Branched Fluorinated Anion Surfactant with CF3CF2CF2C(CF3)2 Group

A novel branched fluorinated anion surfactant 4-(3,3,4,4,5,5,5-heptafluoro-2,2-bis-tri-fluoromethyl-pentyl)benzene lithium phosphonate was successfully synthesized via a four-step route using perfluoro-2-methyl-2-pentene as starting material. The surface activity was investigated. The result showed that the cmc value of the surfactant in water is about 1.5×10-2 mol/L at 298 K and the surface tension of the aqueous solution is 19.2 mN/m at the cmc.

Fluorous phosphines and phosphine oxides

A method of increasing the fluorous nature of a compound includes the step of reacting the compound with or tagging the compound with at least one of a second compound having the formula: wherein R is an alkyl group or an aryl group, n is 1, 2 or 3 and Rs is a spacer group and Rf is a branched fluorous group. A chemical compound having the general formula: wherein n, Rs and Rf are defined above.

Separation of "light fluorous" reagents and catalysts by fluorous solid-phase extraction: Synthesis and study of a family of triarylphosphines bearing linear and branched fluorous tags

Practical syntheses of new triarylphosphines bearing both linear and branched fluorous tags (Rf) are reported. The phosphines have one, two, or all three aryl rings bearing fluorous tags: (Ph)3-nP(C6H4 (CH2)mRf)n. Fluorous-organic partition coefficients have been measured and the retention properties of both the phosphines and the derived phosphine oxides on fluorous reverse phase silica have been studied. While applications relying on liquid-liquid extractive separations of these phosphines may be limited to those bearing three fluorous chains, the technique of solid phase extraction should be broadly applicable to phosphines, phosphine oxides, and derived metal complexes. A parallel platinum-catalyzed allylation of aldehydes with fluorous allyl stannanes illustrates the usefulness of the new fluorous ligands in small-scale synthesis.

Reactions involving fluoride ion. Part 44.1 Synthesis, and chemistry of aromatics with bulky perfluoroalkyl substituents
