The preparation of aminomethyl functionalised silanes based on the α-lithiated amine, (1R,2R)-N,N,N′,N′-tetramethylcyclohexane-1,2-diamine [(R,R)-TMCDA] is reported. This methodology can be applied for the synthesis of mono-aminomethyl substituted systems, but most remarkably also for di- and trifunctionalised compounds. The trapping of the lithiated amine is accompanied by transmetallation reactions
基于α-锂化胺的氨基甲基官能化硅烷的制备, (1 R,2 R)-N,N,N ',N'-四甲基环己烷-1,2-二胺报告了[(R,R)-TMCDA]。该方法学可用于合成单氨基甲基取代的系统,但最显着的是也可用于二官能和三官能化的化合物。锂化胺的捕集伴随着金属转移反应,这取决于反应温度而导致形成(甲硅烷基甲基)硅烷。单官能化系统的卤化锌(II)配合物仅形成立体构型氮原子的一种构型,其中空间上要求更高的取代基表现出伪赤道位置。双官能化和三官能化的系统在(R,R)-TMCDA片段。
