今天就为大家介绍AlMe3(TMA,Trimethyl Aluminum)在胺酯交换反应中的重要应用。 三甲基铝是一个三中心二电子的缺电子体系,在常温常压下一般以二聚体的形式存在,如Al2Me6或(AlMe3)2,其结构上如上图所示。 由于AlMe3很容易自燃,因此市售基本都是以溶液如1 M in hexanes、1 M in toluene和2 M in toluene等...
三甲基铝是一个化合物,化学式是Al2(CH3)6, 可以缩写为Al2Me6, (AlMe3)2或者TMA。它是一种自燃的无色液体,在工业上是很重要的有机铝化合物。它的蒸气散发到空气中后会产生白烟(氧化铝)。 结构与化学键 Al2Me6在常温常压下是二聚体[3],在结构上和乙硼烷相似。像乙硼烷一样,这个化合物同样有两个三中...
另外它是唯一框架由管式结构电焊制成的,不是两个用螺丝拧在一起的个体,而是唯一一个超结实的整体。这样Alme Srl 防盗门拥有很高的防盗性,也避免了那些别的防盗门显而易见的铁边。一般防盗门的框架有两个组件,叫框架和底架。这两个组件从来不会粘在一起,而是中间有空隙。气体和噪音总是由这空隙通过,另外这空...

Herein, we report the regio- and chemoselective reactions of indole with carbamoyl electrophiles in presence of AlMe3. Indole-3-carboxamide was prepared in one-step from a reaction of indole with tertiary carbamoylimidazole in the presence AlMe3. Under conditions for the formation of an aluminium...
