标题:通过氧化氧化将白磷直接转化为多功能磷转移试剂
摘要:用于工业和研究的增值磷化学品的主要原料是白磷(p 4),其中形成 P(III) 化合物的关键中间体是 Pcl 3.由于其高反应性,基于 Pcl 3的合成通常伴随着产物混合物和费力的后处理程序,因此需要一种替代方法来形成可行的 P(III) 转移试剂.我们的氧化氧化概念,其中白磷被选择性地转化为多功能 P 1转移试剂的三氟甲磺酸盐,例如 [p(L N ) 3 ][otf] 3 (L N是阳离子,N基取代基;即,4-二甲氨基吡啶),为实现 P-O,P-N 和 P-C 键提供了一种方便的替代方案,同时避免了 Pcl 3的使用.我们使用 R N E类型的 P 嵌段元素化合物(例如,Ph 3 As 或 Phi)来获得氮路易斯碱 L N和相应的双阳离子 [r N El N ] 2+之间的弱加合物.[r N El N ] 2+ + L N和 [r N E(L N ) 2 ] 2+之间的拟议平衡允许 P 4中所有六个

标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.
