摘要:使用化学计量的烷基或芳基格氏试剂和三氟甲烷磺酸钠(naotf),可以可靠地实现由膦酸酯合成叔膦氧化物,并以优异的收率获得非常好的收率.在没有naotf添加剂的情况下,镁和磷物种的共价配位低聚物占主导地位,产生了非常低的氧化膦收率,但是膦酸酯原料的转化率很高.机理研究表明,五配位的磷物质(不是次膦酸盐)是反应的中间体.使用多种用于直接碳-磷官能化的格氏试剂,将各种各样的膦酸酯转化为氧化膦.这种新方法特别简化了二甲基膦基(rpme 2)型膦通过使用对空气,水和二氧化硅稳定的中间体.为了突出该反应,以优异的产率合成了新的布赫瓦尔德型配体([1,1'-联苯]-2-基二甲基膦或甲基johnphos)和经典的双齿膦双(二苯基膦基)丙烷(dppp).

摘要:The present invention describes the synthesis of silicon-containing monomers and copolymers. The synthesis of a monomer, trimethyl-(2-methylenebut-3-enyl)silane (TMSI) and subsequent synthesis of diblock copolymer with styrene, forming polystyrene-block-polytrimethylsilyl isoprene, and synthesis of diblock copolymer Polystyrene-block-polymethacryloxymethyltrimethylsilane or PS-b-P(MTMSMA). These silicon containing diblock copolymers have a variety of uses. One preferred application is as novel imprint template material with sub-100 nm features for lithography.

摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.
