标题:长期寻求从氧化膦合成季phospho盐的方法:逆反应法†
摘要:季phospho盐(qps)是一类重要的有机磷化合物,以前只能通过涉及亲核性磷的途径获得.我们报告了利用膦氧化物作为亲电子伴侣和格氏试剂作为亲核试剂实现qps的相反方法的实现.通过衍生的卤化salts盐的关键中间体来实现该过程.该路线不受动力学慢和许多母体膦的有限供应的困扰,并且以优异的收率制备了多种qps.

标题 :Preparation of 2-(2'-thienyl) alkylamines and derivatives thereof and synthesis of 4,5,6,7- thieno [3,2-c] pyridine derivatives therefrom
发明人：KHATRI HIRALAL N; DEHOFF BRADLEY S
权利人:SANOFI SA
摘要:An improved process for the synthesis of 2-(2 min -thienyl)ethylamine from suitably functionalized derivatives of 2-(2 min -thienyl)ethanol employing ammonia gas in the presence of a metal salt or liquid ammonia and alkyl ketone as a solvent. The 2-(2 min -thienyl)ethylamine produced by this process is advantageously converted to the carbamic acid salt, which is suitably reconverted to 2-(2 min -thienyl)ethylamine, a useful intermediate in the synthesis of ticlopidine.

标 题:Synthesis of organohalosilane monomers from conventionally uncleavable Direct Process Residue
发明人：LEWIS KENRICK MARTIN; NEELY JOHN DAVID
权利人:LEWIS KENRICK MARTIN; NEELY JOHN DAVID; MOMENTIVE PERFORMANCE MAT INC
摘要:Disclosed herein is a catalytic process for the synthesis of organohalosilane monomers from tetraorganodihalodisilanes and other compounds that are not cleaved during the conventional hydrochlorination of Direct Process Residue. The process is characterized by the use of a catalyst containing (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

标 题:Method for the synthesis of organopolysiloxanes containing carbonate groups
发明人：LERSCH PETER; WEITEMEYER CHRISTIAN
权利人:GOLDSCHMIDT AG TH
摘要:The invention relates to a method for the synthesis of organopoiysiloxanes of the general formula which contains cyclic carbonate groups. The inventive compounds have a high polarity, can be synthesized easily and, because of their compatibility with polar media, find use as additives for dispersion paints or lacquers and for coating the surfaces of pigments and fillers.
