    Synthesis of novel perfluoroalkyl-containing polyethers [Text] / D. N. Bazhin, T. I. Gorbunova, A. Ya. Zapevalov, V. I. Saloutin // Journal of Fluorine Chemistry. - 2009. - Vol. 130, № 4. - P438-443

Аннотация: The synthesis of iodo(perfluoroalkyl)epoxides by radical addition of perfluoroalkyl iodides to allyl glycidyl ether and 1,2-epoxydec-9-ene is described. Dehydroiodination of additional products upon treatment with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) gives unsaturated products. The use of Bu3SnH/Bz2O2 as a reduction reagent of iodo(perfluoroalkyl)allyl glycidyl ethers allows to save oxirane ring. Cationic polymerization of saturated or functional (with iodine or double bond) fluoroalkyl oxiranes under action of catalytic amount of BF3.Et2O proceeds only on epoxide group. In case of poly(9-iod-10-(perfluoroalkyl)-1,2-epoxyalkane) iodine atoms are removed by standard zinc reduction

X-RAY PHOTOELECTRON SPECTROSCOPY -- POLYETHERS
Аннотация: Ultradispersed powders of Cu-Sn alloy were processed by fluorinated polyethers of different compositions. X-ray photoelectron spectroscopy was used to show that a polymeric film no thicker than 2 nm was formed on the surface of particles as a result of processing. The film formed by fluorinated polyethers with a molecular mass of 3000 prevents the interaction of metal particles of Cu-Sn alloy with atmospheric oxygen and provides dielectric properties of the surface

ACETOACETAMIDE-CONTAINING PODANDS -- DIHYDROPYRIMIDINE-CONTAINING PODANDS -- ACETYLKETENE
Аннотация: Reactions of aliphatic aminopodands having different length of the polyether chain with acetoacetic ester and 2,2,6-trimethyl-4H-1,3-dioxin-4-one were studied. The interaction of aminopodands with acetoacetic ester in toluene upon sonication (60A degrees D) or heating (90A degrees D) gave podands with terminal aminocrotonate fragments. The use of dioxinone at the same temperature allowed to transform aminopodands into aliphatic acetoacetamide-containing podands. An asymmetric podand with 2-pyridone fragment was isolated as byproduct from the reaction of dioxinone with 1,5-diamino-3-oxapentane. A three-component Biginelli reaction of acetoacetamidecontaining podands with benzaldehyde and urea in the presence of catalytic amounts of polyphosphoric acid immobilized on nanosized TiO2-SiO2 oxide surface enabled the synthesis of podands with 1,4-dihydropyrimidin-2-(1De)-one fragments.
