摘要:被保护为2-硝基亚苄基缩醛(onba)的二羟基化合物(二醇)的光解以及随后的2-亚硝基苯甲酸酯中间体的酸或碱催化水解导致底物的高效和高产率释放.我们研究了onba光化学的范围和局限性,并扩展了先前描述的两步过程,以表明许多结构变种的受保护二醇也可以通过一锅法释放.鉴于将不对称取代的二醇的缩醛以中等至高区域选择性转化为相应的2-亚硝基苯甲酸酯异构体之一的事实,使用各种实验技术研究了它们的形成机理.实验数据被发现与基于dft的量子化学计算相符,后者显示优先裂解发生在缩电子c-O键附近,更多的吸电子基团(或更少的供电子基团).该研究还揭示了裂解机理的相当复杂性,并且底物中的结构变化可以显着改变反应途径.发现当在还原剂如抗坏血酸存在下从相应的单硫缩醛中释放时,该脱保护策略也适用于2-硫代乙醇.该研究还揭示了裂解机理的相当复杂性,并且底物中的结构变化可以显着改变反应途径.发现当在还原剂如抗坏血酸存在

标 题 :Process for the synthesis of N-(hydroxyalkoxy) substituted hindered amine stabilizers
发明人：GALBO JAMES P; DETLEFSEN ROBERT E; DIFAZIO MICHAEL P; GRACE HENRY C; KUELL CHRISTOPHER
权利人:CIBA SC HOLDING AG
摘要:N-(Hydroxyalkoxy) hindered amine stabilizers are prepared by reacting the corresponding N-oxyl compound with a peroxide or organic hydroperoxide and a catalytic amount of a metal salt or metal-ligand complex in an alcohol solvent. These N-(hydroxyalkoxy) hindered amines are particularly useful as stabilizers for polyolefins, thermoplastic polyolefins and automotive coating compositions.

标题:Synthesis of molybdenum/alkylene glycol complexes useful as epoxidation catalysts
发明人：MARQUIS EDWARD T; KEATING KENNETH P; SANDERSON JOHN R; SMITH WILLIAM A
权利人:TEXACO INC
摘要:Complexes made by reacting an ammonium-containing molybdenum compound with an alkylene glycol in the presence of water at an elevated temperature are described. Mild stripping of the water subsequent to complex formation is preferred. If some of the water is left in the complex, it may serve as an excellent olefin epoxidation catalyst. The ratio of moles of alkylene glycol to gram atoms of molybdenum in the complex forming reaction ranges from 7:1 to 20:1. Ethylene glycol and propylene glycol are the particularly preferred alkylene glycols.

标题:Polycarbonate block copolymers and methods thereof
发明人：ALLEN SCOTT D; DEBNATH DIBYENDU
权利人:SAUDI ARAMCO TECH CO
摘要:The present disclosure relates to block copolymers comprising, and methods of making thereof, a polycarbonate chain linked to a hydrophilic polymer. Such block copolymers may have the formula B-A-B, where A is a polycarbonate or polyethercarbonate chain and B is a polyether. Provided methods are useful in reducing the amount of waste generated from the synthesis of polycarbonates and provide improved thermal stability and high primary hydroxyl content. Provided block copolymers also have utility as additives in enhanced oil recovery methods, and foam polymer applications.
