标题:白磷直接合成单膦
摘要:单磷化合物具有巨大的工业重要性,因为它们在药物,光引发剂和催化配体等应用中发挥着至关重要的作用.白磷 (P 4 ) 是制备所有此类化学品的关键起始原料.然而,目前的生产依赖于间接且低效的多步骤程序.在这里,我们报告了一种直接从 P 4直接合成多种有机和无机单磷物质的简单,有效的"一锅法"合成方法.使用 Tri-N还原 P 4-丁基锡氢化物和随后用各种亲电试剂处理可提供对化学工业至关重要的化合物,它只需要温和的条件和廉价且易于处理的试剂.至关重要的是,我们还证明了三丁基锡试剂的简便高效回收和最终催化使用,从而避免了大量含锡废物的形成.可获得的工业相关产品包括熏蒸剂 Ph 3,还原剂次磷酸和阻燃剂前体四(羟甲基)氯化磷.

标题 :Synthesis of 5-decenyl acetate and other pheromone components
发明人：PEDERSON RICHARD L; GRUBBS ROBERT H
权利人:TILLIECHEM INC
摘要:The present invention relates to syntheses of 5-decenyl acetate, the major component in Peach Twig Borer pheromone, and other pheromone components. The syntheses entails few reaction steps, use commercially available starting materials, and have relatively short process times. A preferred embodiment of the syntheses involves self-metathesizing 1-hexene in the presence of Grubbs' catalyst, [(PCy3)2Cl2]Ru=CHPh. The resulting 5-decene is then reacted with an alcohol or acetate protected hexene under vacuum to yield 5-decenyl acetate. These syntheses produce good yields without the need for expensive or sophisticated equipment.

标题:Unsaturated ester-amides of halogenated alkenes
发明人：D ALELIO GAETANO F
权利人:ALELIO GAETANO F D
摘要:This invention deals with new unsaturated esteramides of alpha , beta -unsaturated polycarboxylic acids derived from halogenated alcohols of the formula wherein R is a divalent hydrocarbon moiety having at least one and no more than 10 carbon atoms, X is a member selected from the class of bromine and chlorine, and R' is a member selected from the class of hydrogen, X and a monovalent hydrocarbon containing at least one and no more than 20 carbon atoms. Typical esteramides are the maleates, fumarates, itaconates and citraconates. These monomers possess fire-retardant properties and are useful for the synthesis of polymers and copolymers.

标 题:Synthesis of olefinic alcohols via enzymatic terminal hydroxylation
发明人：COELHO PEDRO; CHEN MIKE M Y; MEINHOLD PETER; CHO CATHERINE MEE-HIE; BUI VU; HEEL THOMAS
权利人:PROVIVI INC
摘要:In certain aspects, the present invention provides methods for producing terminally hydroxylated alkenes and alkynes by contacting an unsaturated or saturated hydrocarbon substrate with a hydroxylase enzyme. Exemplary terminal hydroxylases useful for carrying out the methods of the invention exhibit strong selectivity towards one terminal carbon of a hydrocarbon substrate and include, but are not limited to, non-heme diiron alkane monooxygenases, cytochromes P450 (e.g., cytochromes P450 of the CYP52 and CYP153 family), as well as long chain alkane hydroxylases. In some embodiments, the terminally hydroxylated alkene or alkyne is further converted to a terminal alkenal. In certain embodiments, terminally hydroxylated alkenes and alkynes are useful as insect pheromones which modify insect behavior. In other embodiments, terminally hydroxylated alkenes and alkynes are useful intermediates for producing pheromones via acetylation or oxidation of the alcohol moiety.
