标题 :Process for synthesis of silane dipeptide analogs
发明人：SIEBURTH SCOTT MCNEILL; BO YINGJIAN
权利人:SIEBURTH SCOTT MCNEILL; BO YINGJIAN; Temple University—Of the Commonwealth System of Higher Education
摘要:The invention provides a method of preparing silane dipeptide analogs, comprising the steps of treating a solution of a substituted 1,2-oxasilolane with lithium metal to form a solution of the dilithium salt of a substituted 3-hydroxypropylsilanol, and reacting the solution of the dilithium salt of the substituted 3-hydroxypropylsilanol with a substituted enamine.

标 题 :Manganese catalyzed photopolymerization of fluorinated monomers
发明人：ASANDEI ALEXANDRU D
权利人:UNIV CONNECTICUT
摘要:The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations.

标 题:Method of Synthesis of Arylsulfur Trifluorides and Use as in situ Deoxofluorination Reagent
发明人：DOLBIER JR WILLIAM R; XU WEI
权利人:DOLBIER JR WILLIAM R; XU WEI; FLUOROTECH LLC; OAKWOOD PRODUCTS INC
摘要:The invention is a method of synthesizing Arylsulfur Trifluorides, such as Fluolead, by reacting BR 2 and KF (or suitable alkali metal fluoride) in acetonitrile (or other suitable solvent). The invention also comprises using the Fluolead (or its substitutes), thus prepared, in situ as deoxofluorination reagents with a suitable aldehyde, ketone, or alcohol such as one selected from the group consisting of benzaldehyde Benzaldehyde, p-Bromobenzaldehyde, p-Tolualdehyde, Acetophenone, 2-Butanone, or Isobutyraldehyde, wherein the mixture is heated to reflux until completion. The respective products are then isolated after extraction by hexane and destruction of the sulfinyl fluoride co-product.

标题:Synthesis of thioether containing trialkoxysilanes
发明人：GARRELL ROBIN L; TUCKER-SCHWARTZ ALEXANDER K
权利人:GARRELL ROBIN L; TUCKER-SCHWARTZ ALEXANDER K; UNIV CALIFORNIA
摘要:The invention relates to a radical-initiated thiol-ene or thiol-yne “clickâ€? reaction that provides a simple and efficient route to diverse trialkoxysilanes. Trialkoxysilanes made in this way are obtained in quantitative to near-quantitative yields with high purity without any or minimal purification. A wide range of functional groups is tolerated in this approach, and even complex alkenes click with the silane precursors. The modular nature of these radical-based thiol-ene or thiol-yne “clickâ€? reactions allows a wide variety of pendant groups to be coupled to silane compounds that can then be coupled to a wide variety surfaces in order to modify their material properties. Consequently, such radical initiated thiol-ene and thiol-yne reactions provide facile and efficient methods for preparing an enormous number of surface-active functional trialkoxysilanes.
