摘要:Precursors and methods for the synthesis of mono- and difunctionalized acetylenes are described. The invention includes novel tricoordinate iodonium transfer reagents and novel alkynyldi(phenyliodonium) salts, both of which are precursors for the functionalized acetylenes. The iodonium transfer reagents take the general form of mixed iodonium sulfonates PhI + (X)OSO 2 R f , where X may be OAc, NHAc, NCO, or CN. These mixed iodonium sulfonates are produced by reaction of iodosobenzene with certain substituted trimethylsilanes. n To make the alkynyldi(phenyliodonium) salt PhI + C.tbd.CI + Ph•2 R f SO 3 - ,a mixed iodonium sulfonate is reacted with a bistin acetylene of the kind R' 3 SnC.tbd.CSnR' 3 . Alternatively, the reaction may be performed with disubstituted tin diacetylenes to produce PhI + C.tbd.C-C.tbd.CI + Ph•2 R f SO 3 - to produce a dialkynyldi(phenyliodonium) salt. Subsequent reaction of a nucleophile with the alkynyldi(phenyl-iodonium) salt or dialkynyldi(phenyliodonium) salt produces a difunctional acetylene or a difunctional 1,3-diyne, respectively.

标 题 :Method for in-site synthesis of transparent conductive coating of poly(3,4-ethylenedioxythiophene)/nano silver

摘要:A method for in-site synthesis of transparent conductive coating of poly(3,4-ethylenedioxythiophene)/nano silver hybrid on transparent substrate is provided. Transparent substrate with oxidant coating containing silver salt is immersed into 3,4-ethylenedioxythiophene (EDOT) solution. The oxidant turns EDOT monomer to poly(3,4-ethylenedioxythiophene) (PEDOT) coating on the transparent substrate; meanwhile, the silver salt itself is reduced to nano silver by the EDOT monomer, resulting in a nano silver-doped PEDOT coating. Thereby, a transparent conductive film made of PEDOT/nano silver coating on transparent substrate is obtained. The transparent conductive film with PEDOT/nano silver coating prepared in the present invention possesses the advantages of high electrical conductivity, optical transparency and environmental stability.

摘要:Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.
