标题:来宾反应驱动的笼子转为连体的双笼有丝分裂样宿主转化.
摘要:我们在这里报告客体反应诱导的有丝分裂样宿主转化,从已知的pd 4 L 2笼1到具有两个独立腔的连体pd 6 L 3双笼2.发现笼子1的疏水腔中1-羟甲基-2-萘酚(g1)(一种已知的邻醌甲基化物(o-Qms)前体)的包封对于实现笼子到双笼的转化至关重要.纳米腔体内的受限g1分子经历自偶联二聚化反应以形成2,2'-二羟基-1,1'-二萘基甲烷(g2),然后触发笼子进入双笼有丝分裂.通过g2的直接模板化,同样的转换也以更快的速度进行,从而确认了诱导拟合转换机制.(的结构g2)2 ⊂ 2主-客体复合物已通过x射线晶体学研究,其中顺式-反式-对构象上的一个桥联配体开关显露建立.

标 题 :Improved process for synthesis of hindered amine stabilizers for polymeric materials
发明人：LAI JOHN TA-YUAN
权利人:GOODRICH CO B F
摘要:Process for the synthesis of hindered polysubstituted α-amino acetamides by reaction of a secondary amine with an α-halo acetamide in a basic organic reaction medium and in the presence of a phase transfer catalyst. The product thus obtained can comprise a multifunctional compound having one or more hindered amino moieties. These compounds are highly effective as UV stabilizers in a variety of plastics, especially the alpha monoolefins.

标 题:Synthesis of modified epoxy resins for cathodic electrodeposition with catalyst deactivation and diol modification
发明人：REUTER HARDY; JOUCK WALTER; OTT GUENTHER
权利人:BASF LACKE & FARBEN
摘要:Epoxy resins for preparing water-dispersible binders for cathodic electrodeposition coating materials, the epoxy resin being preparable by reacting a) polyepoxides having at least one glycidyl group per molecule b) and, optionally, up to 60% by weight, based on the overall epoxy resin reaction product, of aliphatic and/or alicyclic hydroxy compounds having preferably two or on average less than two hydroxyl groups per molecule and a molecular weight of less than 9000 g/mol, c) in the presence of a catalyst consisting of neutral metal salts, such as alkali metal salts and alkaline earth metal salts, zinc salts and nickel salts of tetrafluoroboric, tetrachloroboric, hexafluoro- antimonic,hexachloroantimonic,hexafluorophosphoric, perchlorate and periodic acid, and d) adding a deactivating agent which prevents the epoxy groups reacting further or effectively reduces the rate of such reaction as soon as the phenolic hydroxyl groups have already substantially reacted and at least 0.6% by weight of epoxy groups are still present, based on the overall weight of the epoxy resin reaction product.\\!

发明人：LAI JOHN T
权利人:GOODRICH CO B F
摘要:Process for the synthesis of hindered polysubstituted alpha -amino acetamides which comprises first reacting an alpha -haloacetamide with a base to form an intermediate alpha -lactam which in turn is reacted with a primary or secondary amine. The product thus obtained can comprise a multifunctional compound having one or more hindered amino moieties. These compounds are highly effective as UV stabilizers in a variety of plastics, especially the alpha monoolefins.

标 题:UV-Light-stabilized compositions containing substituted 1,5-diazacycloalkanes, novel compounds and synthesis thereof
发明人：LAI JOHN T; SON PYONG N
权利人:GOODRICH CO B F
摘要:Novel polysubstituted 1,5-diazacycloalkanes and polysubstituted 2-keto-1,5-diazacycloalkanes are powerful stabilizers for materials subject to ultraviolet (UV) light degradation, particularly for polyolefins. The cyclic compounds of this invention have (a) a fixed three-carbon bridge between the N1 and N5 atoms of the diaza ring, the remaining portion of the ring having a variable length bridge of two or more carbon atoms, (b) an N-adjacent carbon atom of the diaza ring is polysubstituted, that is, has two substituents which may be cyclizable. Compositions containing (a) the polysubstituted 1,5-diazacycloalkanes and polysubstituted 2-keto-1,5-diazacycloalkanes of this invention, and (b) prior art polysubstituted 1,5-diazacycloalkanes and polysubstituted 2-keto-1,5-diazacycloalkanes, exhibit excellent stability to UV light. A novel synthesis for preparing polysubstituted 2-keto-1,5-diazacycloalkanes is disclosed.
