标 题:Methods for synthesis of graft polymers
发明人：GAUTHIER MARIO; YUAN ZHONGSHUN
权利人:UNIV WATERLOO
摘要:A process for the synthesis of arborescent polymers comprises epoxidation of a first polymer and grafting thereto a second polymer having groups reactive to the epoxide groups on the first polymer. The epoxidation and grafting steps can be repeated. In an additional embodiment, the present invention provides a one-pot method for the synthesis of arborescent polymers. In a reaction pot, a first polymer is copolymerized and then reacted with an activating compound in order to generate a polyfunctional macroinitiator. Monomers are then added to the reaction pot, the monomers having functional groups reactive towards reactive sites on the first polymer.

标题:Apparatus and method used in multiple, simultaneous synthesis of general compounds

摘要:The apparatus and method of the present invention provides for conducting simultaneous multiple synthesis of general compounds, which often takes place under varied uneven conditions requiring heating, cooling, agitation, reagent/solvent additions to the reactor contents at each reaction vessel location, supply and maintenance of inert atmosphere and means to facilitate the reflux of the reactor contents. Thus, it becomes necessary to monitor and control the reaction conditions during the simultaneous multiple synthesis of general compounds. The apparatus allows the user to connect various independently controlling and conveying means to each reaction vessel through multiple ports provided on a stopper mounted on each reaction vessel. The apparatus of the present invention permits user to readily access the reaction vessels without interrupting the reactions occurring in the adjacent reaction vessels. The unique geometry and shape of the stopper allows positioning of multiple ports, while still providing the stopper with a compact size. As a result, a large array of reaction vessels can be accommodated in the device of the present invention without significantly increasing the overall size of the apparatus. Some of the general compounds that can be readily synthesized by the apparatus and the method of the present invention include inorganic compounds as well as organic compounds, such as oligomers, polymers, agricultural chemicals, drugs, peptides and oligonucleotides.

标题:Method of regioselective synthesis of substituted benzoates
发明人：KRAUS GEORGE A
权利人:KRAUS GEORGE A; UNIV IOWA STATE RES FOUND INC
摘要:A method of synthesis of para-substituted benzoate esters and acids is provided, wherein the para-substituted regioisomer is obtained substantially free of the meta-substituted impurity, the method comprising contacting a coumalate ester or acid and an unactivated alkene at elevated temperature in the presence of a metal oxidation catalyst and an oxidant. The metal oxidation catalyst can be palladium, such as palladium on carbon, and the oxidant can be the oxygen gas in ambient air. The reaction can be carried out without solvent or in high boiling hydrocarbon solvents such as mesitylene. When the unactivated alkene is a monosubstituted alkene, yields of at least about 50 or 60% of para-substituted ester and acid products, respectively, are obtained, substantially free of the regioisomeric meta-substituted impurity.
