摘要:在三氟乙酸钯催化的环己烯和相关环烯烃脱氢成芳烃中,分子氧可以代替牺牲性烯烃作为氢受体.均相系统的主要缺点之一是三氟乙酸钯在高温下以钯(0)形式沉淀的趋势.更好的配体的使用提供了可以在更高温度下运行的催化剂,尽管它们的反应性不如三氟乙酸钯.

标题 :Synthesis of hydrogensilsesquioxane and organohydridosiloxane resins
发明人：HACKER NIGEL P; KRAJEWSKI TODD; LEFFERTS SCOTT
权利人:ALLIED SIGNAL INC
摘要:Novel processes for preparing hydridosiloxane and organohydridosiloxane resins are disclosed. The processes of the invention broadly provide for the steps of contacting a silane monomer with a solid state catalyst in the presence of a reaction mixture that includes a nonpolar, e.g., hydrocarbon, solvent, and a polar solvent, e.g., alcohol and water. The process is conducted under conditions effective to catalytically convert said silane monomer into hydridosiloxanes and organohydridosiloxanes. Recovery of the products is advantageously aided by the ease of separating the solid state catalyst from the reaction mixture. Hydridosiloxanes and organohydridosiloxanes resins produced by the processes of the invention are also provided.

标题:Synthesis of siloxane resins
发明人：HACKER NIGEL; FIGGE LISA; LEFFERTS SCOTT
摘要:Novel processes for preparing hydridosiloxane and organohydridosiloxane resins are disclosed. The processes of the invention broadly provide for the steps of contacting a silane monomer with a phase transfer catalyst in the presence of a reaction mixture that includes a nonpolar, e.g., hydrocarbon, solvent, and a polar solvent, e.g., alcohol and water. The process is conducted under conditions effective to catalytically convert said silane monomer into hydridosiloxane and organohydridosiloxane resins. Recovery of the products is advantageously aided by the ease of separating the phase transfer catalyst from the dual phase reaction mixture by separating the immiscible polar solvent carrying the catalyst from the nonpolar solvent that carries the product. Hydridosiloxane and organohydridosiloxane resins produced by the processes of the invention are also provided.

标题 :Synthesis of alkyl cycloalkyl dialkoxysilanes
发明人：BAND ELLIOT I; EBERHART SUZANNE T
权利人:AKZO AMERICA INC
摘要:Alkyl cycloalkyl dialkoxysilanes (e.g., methyl cyclohexyl dimethoxysilane) can be prepared by reaction of an alkyl trialkoxysilane (e.g., methyl trimethoxysilane) with a Grignard reagent containing the cycloalkyl moiety derived in the final end-product (e.g., a reagent formed by reacting cyclohexyl chloride and magnesium metal). The reaction is run in the absence of ether solvent, the Grignard reagent is preferably formed in situ by the reaction of magnesium metal and cyclohexyl halide, and agitation is used to promote the reaction. Advantageously, a catalyst, such as iodine, is used to promote the reaction.

标题 :Manufacture of 3-halosulfonylthiophene-carboxylic acid compounds
发明人：ROSSY PHILLIP A; HOFFMANN WERNER; MUELLER NORBERT
权利人:BASF AG
摘要:3-Halosulfonylthiophene-carboxylic acid compounds are manufactured by reacting 3-ketothiophane-carboxylic acid compounds with sulfonic acid compounds, reacting the end product from the 1st reaction stage with alkali metal polysulfides, reacting the end product from the 2nd stage with a dehydrogenating agent and finally reacting the end product from the 3rd stage with halogen and water. The products are starting compounds for the manufacture of drugs, dyes and crop protection agents and have an anti-inflammatory, analgesic and anti-rheumatic action. In particular, the end products I are starting materials for the manufacture of sweeteners which are non-toxic and free from an after-taste, flavor-improving agents, diabetic aids and feedstuffs, and provide the means of a simple and economical synthesis of thiophene-saccharins.

摘要:Disclosed is a method for producing, from an aqueous basic composition, a primary arsine having one hydrocarbyl group bonded directly to As, the basic composition having been obtained from the combination of components comprising an alkali metal arsenite and a reactive hydrocarbyl halide by combining the aqueous composition with an acidic, nascent hydrogen-generating reducing agent to produce the primary arsine directly from the aqueous composition without isolation of the primary arsonic acid intermediate.
