摘要:在 180-220 oc 的钢制高压釜中,水氨对六氟苯的作用会产生异构的四氟苯二胺和 2,4,5-三氟苯-1,3-二胺混合物.加氢脱氟产物的含量很大程度上取决于反应温度和时间.四氟苯-1,3-二胺与氨水在钢制高压釜中于 200 oc 下发生氢氟化反应,反应生成 2,4,5-三氟苯-1,3-二胺;当添加 Nh4F 和/或 Fecl3 时,会额外反应生成 2,5-二氟苯-1,3-二胺.六氟苯在玻璃反应器中与水氨或在钢制高压釜中与无水氨(与无相溶剂的混合物)进行双氨基脱氟反应时,不会形成氢脱氟产物.

发明人：SCHINSKI WILLIAM; GOLDMAN ALAN; GUNNOE THOMAS B; WEBSTER-GARDINER MICHAEL S; SCHWARTZ NICHOLE
权利人:UNIV VIRGINIA PATENT FOUNDATION
摘要:Catalytic methods for synthesis of super linear alkenyl arenes and alkyl arenes are provided. The methods are capable of synthesizing super linear alkyl and alkenyl arenes from simple arene and olefin starting materials and with high selectivity for linear coupling. Methods are also provided for making a 2,6-dimethylnapthalene (DMN) or 2,6-methylethylnapthalene (MEN).

摘要:A method of making a porphyrin (I) is carried out by condensing (i) a bis(imino)dipyrromethane of Formula II: n nwith (ii) a dipyrromethaneto produce a reaction product; then (b) optionally oxidizing said reaction product with an oxidizing agent; and then (c) optionally demetallating said reaction product to produce the porphyrin. Methods of making compounds of Formula II are also described.

权利人:OPTIMER PHOTONICS INC
摘要:In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a Ï€-donor conjugated to a Ï€-acceptor through a Ï€-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.
