标 题 :Process for synthesis of aromatic sulfides
发明人：HAY ALLAN S; WANG ZHI Y
权利人:HAY ALLAN S; WANG ZHI Y
摘要:Aromatic sulfides including diarylsulfides and poly(arylene sulfides) are produced in a novel synthesis in high yield under moderate conditions by heating an aromatic disulfide in the presence of aromatic halide, in which the halide is chloride, bromide or iodide; the diaryl sulfides are useful precursors and starting materials for a range of compounds and the poly(arylene sulfides) are important high temperature engineering thermoplastics.

标 题:Methods for electrochemical synthesis of organoiodonium salts and derivatives
发明人：PLETCHER DEREK; WEINBERG NORMAN L
权利人:CORNELL DEV LLC
摘要:Organoiodonium salts, including certain novel symmetrical and unsymmetrical diaryliodonium;. polyiodonium and cyclic iodonium salts are synthesized by a significantly improved electrochemical coupling reaction which provides greater control and selectivity over the end product produced. Reaction mixtures comprising aryliodides and/or aromatic substrates are electrolyzed in novel reaction mediums comprising strong acid electrolyte, lower carboxylic acid, and preferably in the presence of acid anhydride in amounts >10 percent by-weight, and up to 50 percent by-weight or more, to provide a high degree of product selectivity, and at yields which can even be quantitative. The methods are conducted by introducing the electrolysis reaction mixture into an undivided electrochemical cell equipped with a cathode and preferably a conductive carbon anode. A voltage is applied across the electrodes to electrolyze the reaction mixture to generate selectively mainly iodonium cation, or if desired, only aryliodide esters, at the anode.

摘要:The present invention relates to 1,2,3-triazole containing artemisinin compounds and process for preparation thereof. Described herein is the synthesis, bioassay results and usefulness of the artemisinin derived compounds resulting from 1,3-dipolar cycloaddition reaction of artemisinin derived azide or alkyne with aliphatic or aromatic diazides. These 1,2,3-triazole containing artemisinin derived compounds embodied in this document are found to be active against various cancer cell-lines.

标题:Oligomeric hydroxy arylether phthalonitiles and synthesis thereof
发明人：KELLER TEDDY M; DOMINGUEZ DAWN D
权利人:US NAVY
摘要:An aromatic ether oligomer or polyaromatic ether comprising the formula:n n O—Ar n ;n nwherein Ar is an independently selected divalent aromatic radical; formed by reacting a dihydroxyaromatic with a dihaloaromatic; and wherein the reaction is performed in the presence of a copper compound and cesium carbonate. The polyaromatic ether is formed when neither the dihydroxyaromatic nor the dihaloaromatic is present in an excess amount. The aromatic ether oligomer is formed by using an excess of either dihydroxyaromatic or dihaloaromatic. A phthalonitrile monomer comprising the formula:n n nformed by reacting a 3- or 4-nitrophthalonitrile with a hydroxy-terminated aromatic ether oligomer. A thermoset formed by curing the phthalonitrile monomer. Processes for forming all the above.
