标题:Synthesis of succinimides and quaternary ammonium ions for use in making molecular sieves
发明人：SCHMITT KIRK D; ZUSHMA STEPHEN; BURTON ALLEN W
权利人:EXXONMOBIL CHEMICAL PATENTS INC
摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

标 题:Direct synthesis of organotin alkoxides
发明人：JILEK ROBERT E; REED CHRISTOPHER J; NOVAS BRYAN
权利人:INPRIA CORP
摘要:Synthesis techniques are described for forming organotin trialkoxide compounds via direct alkylation of tin alkoxides. A first method involves reacting an alkali metal tin trialkoxide with an organohalide compound (RXn, where X is a halide atom and n≥1) to form a monoorgano tin trialkoxide represented by the formula R[Sn(OR′)3]n. The method can be used to form polytin trialkoxide compounds with a plurality of radiation sensitive C—Sn bonds. R and R′ include organo groups and can optionally comprise hetero-atoms and/or unsaturated bonds. A second method involves the ultraviolet light-driven reaction of a di-tin tetraalkoxide with an organohalide compound (RX) to form a monoorgano trialkoxide represented by the formula RSn(OR′)3. A third method involves the visible or ultraviolet light-driven reaction of a di-tin tetraalkoxide or an alkali metal tin trialkoxide with an fluorinated organohalide compound (RFX) to form a fluorinated monoorgano trialkoxide represented by the formula RFSn(OR′)3. The disclosed methods provide for high mono-organo specificity. Corresponding organotin trialkoxide compositions are also described. The compositions are useful for radiation patterning, especially with EUV radiation. The organotin trialkoxide compositions may be formed as radiation-patternable coatings on substrates.

权利人:USA FORTESCUE IP INC
摘要:An ion exchange polymer has an ionomer structure containing poly(phenylene) compound integrated with functionalized poly(fluorene). The ion conducting co-polymer includes a poly(fluorene) compound and a poly(phenylene) compound covalently bonded together. The poly(fluorene) compound has a 9H-fluorene structure that is a polycyclic aromatic hydrocarbon having a center ring with five carbon atoms, and a benzene ring on each of opposing sides of said center ring. The poly(phenylene) compound is covalently bonded to each of the pair of benzene rings of the poly(fluorene) compound. A pair of sidechains extends from the center ring of the poly(fluorene) compound to a respective terminal group. The terminal groups are configured on sidechains of the poly(fluorene) compound and can be converted into functional groups such as quaternary ammonium or n-methyl piperidine functional groups. The ion exchange polymer may include a porous scaffold support.
