标题:Synthesis of methyl malvalate and methyl 5,6-methano-5-undecenoate
发明人：GENSLER WALTER J
权利人:US AGRICULTURE
摘要:This invention relates to the preparation of methyl malvalate, methyl 5,6-methano-5-undecenoate and the preparation of some new intermediates. Malvalic acid, the major cyclopropene component in cottonseed oil, has been synthesized. When 1-chloro-7-hexadecyne reacts with diazoacetic ester in the presence of copper bronze, the ester of 1-chloro-7,8-carboxymethano-7-hexadecene is formed. Treating the corresponding acid chloride with zinc chloride causes loss of carbon monoxide. Either sodium borohydride or lithium aluminum hydride reduces the resulting cyclopropenium compound to 1-chloro-7,8-methano-7-hexadecene. Replacing the chloro group with cyano yields malvalonitrile, which can be converted to methyl malvalate. An analogous sequence of steps has been applied to 1-chloro-4-decyne to produce methyl 5,6-methano5-undecenoate. An alternate synthesis of methyl malvalate starts by using 1-chloro-7-hexadecyne as the precursor for methyl 8heptadecynoate. This acetylenic ester is converted to 8,9carboxymethano-8-heptadecenoic acid, the diacid chloride of which decarbonylates selectively in the presence of metallic chlorides to form the cyclopropenium-acid chloride. After esterification the resulting cyclopropenium-ester is reduced with borohydride to methyl malvalate.

标 题:Method for the direct synthesis of organo-tin chlorides, and the use of such chlorides
发明人：MALGUZZI ROMUALDO; SANDRI MAURIZIO; ROSENTHAL MICHAEL; PUERZER ALBERT W
权利人:BAERLOCHER GMBH
摘要:The invention concerns a method of synthesizing directly organo-tin chlorides of the formula RnSnCl4-n, in which n = 1 or 2 and R is a straight-chain, branched-chain or cycloaliphatic alkyl rest with 4 to 18 C-atoms, by reacting tin(II)-chloride with alkyl chlorides. The method is characterized in that the reaction is carried out in the presence of amines of the general formula A: R1aN[(CH2CH2O)m CH2CH2OR2]3-a and/or substituted ammonium chlorides of the formula B: R1bN[(CH2CH2O)mCH2CH2OR2]4-b Cl in which a = 0, 1 or 2; b= 0, 1, 2 or 3; R1 is a straight-chain, branched-chain or cycloaliphatic alkyl group with 2 to 24 C-atoms, or an aryl, alkylaryl or substituted-aryl group, and if a = 2 or b = 2 or 3, the R1 groups may be the same or different; R2=H is a straight-chain or branched-chain alkyl group with 1 to 20 C-atoms, or an aryl, substituted-aryl or alkylaryl group; and m = 1 to 20. Organo-tin chlorides produced in this way are particularly suitable for use as intermediates in the preparation of thermostabilizers for PVC resins.

摘要:Inorganic membranes such as zeolite membranes or other molecular sieve membranes can be provided by using siliconee, polymer material as starting material. A thin film zeolite membrane or a thin film membrane formed of interlocking zeolite crystals can be provided. Water soluble or water insoluble silicones can be treated in a basic solution under conditions and with an appropriate structure directing template, suitable aluminum content and at a temperature that is appropriate for growing a desired inorganic crystal framework. Heteroatoms can be included in the crystalline framework.
