Shao, Hui,Jiang, Li,Meng, Wei-Dong,Qing, Feng-Ling
, p. 89 - 91 (2003)
A novel perfluoroalkyl-containing quaternary ammonium salt 5 was designed and synthesized. Consequently, the antimicrobial activities of compound 5 were measured with Escherichia coli 8099 as a Gram-negative strain and Staphylococcus aureus ATCC 6538 as a
Fluorous biphasic catalysis. 2. Synthesis of fluoroponytailed amine ligands along with fluoroponytailed carboxylate synthons, [M(C8F17(CH2)2CO2) 2] (M = Mn2+ or Co2+)

Fluorous biphasic catalysis (FBC) is a relatively new concept for homogeneous catalysis where the fluorocarbon soluble catalyst resides in a separate phase from the substrate and products. Therefore, separation of the catalyst and the products occurs by a

Syntheses of fluorous propenes from 3-perfluoroalkyl-2-iodo-1-propanols
Szíjjártó, Csongor,Ivanko, Peter,Takács, Ferenc T.,Szabó, Dénes,Rábai, József
, p. 386 - 389 (2008)
3-(Perfluoroalkyl)-1-propenes are obtained in excellent yields up to 100-g quantities by deiodination-dehydroxylation reactions of the easily accessible 2-iodo-3-(perfluoroalkyl)-propanols with red phosphorus and catalytic amounts of iodine or with an SnCl2/POCl3 reagent pair in pyridine (fluorous Cornforth reaction). Both methods afford fluorous propenes in high GC purity, the former one has high atom-economy and proceeds safely if the fluorous iodohydrin precursors are added in increments; for the solid ones using a 'hot-melt' dropping funnel. The title fluorous propenes are effectively isolated by co-distillation with pyridine.
Mesophase structure of low-wetting liquid crystalline polyacrylates with new perfluoroalkyl benzoate side groups
Martinelli, Elisa,Paoli, Francesca,Gallot, Bernard,Galli, Giancarlo
experimental part, p. 4128 - 4139 (2011/10/30)
The synthesis, thermal behavior, bulk microstructure, and wettability of new polyacrylates carrying spaced 4-perfluorohexylpropyl benzoate and 4-perfluorooctylpropyl benzoate units in the side groups were Investigated. X-ray diffraction analysis proved the formation of different smectic mesophases (SmI2, SmF2, and SmC2) and the evolution of their structures and lattice parameters with temperature. The mesophase polymorphic behavior depended on the length of the perfluorinated chain segment in the repeat unit. The electron density profiles along the smectic layer normal were drawn and provided a deeper insight into the packing of the side chains in a tilted, double layer structure. Thin polymer films were cast from solution, and their low wettability was established by measurements of contact angles with different probing liquids. We suggest that the hydrophobicity and lipophobicity of the films are enhanced by the mesophase surface structure which is mediated by the high-order, mesophase bulk structure.
Towards oligosaccharide library synthesis by fluorous mixture method
Tojino, Mami,Mizuno, Mamoru
scheme or table, p. 5920 - 5923 (2009/04/05)
The synthesis of an oligosaccharide library by a fluorous tag method is reported here. Several acceptors and donors were mixed and glycosylated. The reaction mixture was purified by chromatography over fluorous HPLC to provide disaccharides in order of increasing fluorine content of the tag. This method could be applied to oligosaccharide libraries consisting of two sets of structural isomers.
