标 题:Use of alpha-di(lower alkoxy) anthraquinones in the synthesis of Alizarin Saphirols
发明人：WHITE DAVID L; FITZPATRICK JOSEPH W
权利人:TOMS RIVER CHEMICAL CORP
摘要:Alpha-dihydroxyanthraquinones used as intermediates in the synthesis of many dyestuffs, such as the Alizarin Saphirols (e.g. Color Constitution No. 63000, 63005, 63010, 63011, 63315 and 63610) can be replaced on an equimolar basis by alpha-di(lower alkoxy)anthraquinones. The alpha-di(lower alkoxy) anthraquinones can be converted in a single step, by treatment with oleum, to the corresponding alpha-dihydroxyanthraquinone-beta-disulfonic acids in almost quantitative yield. The corresponding diamine is obtained by dinitrating followed by reduction of the nitro groups. The known intermediate, leuco 1,4,5,8-tetrahydroxyanthraquinone (see C.I. No. 62500) can be obtained either by reduction of the diamine or by reduction of the dinitro compound. In one embodiment, the alpha-di(lower alkoxy)anthraquinone is obtained from dinitroanthraquinone by treatment thereof with methanol and KOH.

标 题 :Performance of energy storage devices: potential areas for dendritic chemistry involvement
发明人：NEWKOME GEORGE R
权利人:NEWKOME GEORGE R
摘要:A compound consists of a fractal-like, plain or organometallic array useful for energy storage devices. A dendrimer useful in the synthesis of the fractal-like compound includes a single ligating moiety bound to a surface of each quadrant of the dendrimer. A method of making metallo-based (macro) molecules includes the steps of combining monomers selected from the group consisting of bipyridal- and terpyridal-based ligands with connecting metals and self assembling macrocycles wherein the monomes are interconnected by the metals.

标 题:Process for the preparation of 1,4-diamino-2,3-dicyanoanthraquinone
发明人：SCHAULIN RUDOLF; GRELAT MAURICE
权利人:CIBA GEIGY CORP
摘要:The invention relates to a process for the preparation of 1,4-diamino-2,3-dicyanoanthraquinone, starting from 1,4-diaminoanthraquinones, or salts thereof, of the formula ##STR1## wherein n is 0, 1 or 2. To introduce the two cyanide radicals, the starting material is treated, in the presence of an oxidizing agent, with a compound which donates cyanide ions. The process comprises using as solvent a mixture of a carboxamide, an N-alkylated carboxamide or a lactam and water, which mixture contains more than 10% by weight of water. n 1,4-Diamino-2,3-dicyanoanthraquinone is an important intermediate for the synthesis of textile dyes.

标题:Synthesis of macrocyclic tetraamido compounds and new metal insertion process
发明人：HORWITZ COLIN P; GHOSH ANINDYA
权利人:UNIV CARNEGIE MELLON
摘要:An improved method of synthesizing a macrocyclic tetraamido compound includes protecting the amino portion of an amino carboxylic acid to form a protected amino carboxylic acid; exposing the protected amino carboxylic acid to a first solvent, preferably a hydrocarbon solvent, such as toluene or 1,2-dichloroethane, dichloromethane, dibromomethane and 1,2-dibromoethane. The carboxylic acid portion of the protected amino carboxylic acid is then converted to an activated carboxylic acid by one of esterification or acid halide formation, to form a protected amino activated carboxylic acid derivative. The protected amino activated carboxylic acid derivative is reacted with a diamine in the presence of a second solvent, such as THF or ,2-dichloroethane, dichloromethane, dibromomethane and 1,2-dibromoethane, to form a protected diamide diamine intermediate. Following deprotection, the diamide diamine intermediate is reacted with an activated diacid, such as an activated malonate, oxalate or succinate derivative to form the macrocyclic tetraamido compound. The macrocyclic tetraamido compound may further be complexed with a transition metal.

标题 :Synthesis of tertiary amine oxides
发明人：PRABHU VAIKUNTH S
权利人:GEN ELECTRIC
摘要:A process is provided for the manufacture of free-flowing solid tertiary amine oxides having N-nitrosodimethylamine levels of less than about 250 ppb. The process comprises heating a mixture of a tertiary amine, a polar hydroxy alkyl solvent, an organic acid, and aqueous hydrogen peroxide, followed by removal of the solvent and water, preferably by azeotropic removal. The resultant tertiary amine oxides have good color without bleaching and are useful without further purification.
