The structural chemistry of eleven donor complexes of the important Brønsted base potassium 1,1,1,3,3,3-hexamethyldisilazide (KHMDS) has been studied. Depending on the donor, each complex adopted one of five general structural motifs. Specifically, in this study the donors employed were toluene (to give polymeric 1 and dimeric 2), THF (polymeric 3), N,N,N',N'-tetramethylethylenediamine (TMEDA) (dimeric 4), (R,R)-N,N,N',N'-tetramethyl-1,2-diaminocyclohexane [(R,R)-TMCDA] (dimeric 5), 12-crown-4 (dimeric 6), N,N,N',N'-tetramethyldiaminoethyl ether (TMDAE) (tetranuclear dimeric 8 and monomeric 10), N,N,N',N'',N''-pentamethyldiethylenetriamine (PMDETA) (tetranuclear dimeric 7), tris[2-dimethyl(amino)ethyl]amine (MeTREN) (tetranuclear dimeric 9) and tris{2-(2-methoxyethoxy)ethyl}amine (TMEEA) (monomeric 11). The complexes were also studied in solution by H and C NMR spectroscopy as well as DOSY NMR spectroscopy.
对重要的布朗斯特碱1,1,1,3,3,3-六甲基二硅氮钾（KHMDS）的十一种供体配合物的结构化学进行了研究。根据供体的不同，每种配合物采用了五种一般结构模式中的一种。具体而言，在本研究中使用的供体有甲苯（得到聚合物1和二聚体2）、四氢呋喃（聚合物3）、N,N,N',N'-四甲基乙二胺（TMEDA）（二聚体4）、(R,R)-N,N,N',N'-四甲基-1,2-二氨基环己烷[(R,R)-TMCDA]（二聚体5）、12-冠-4（二聚体6）、N,N,N',N'-四甲基二氨基乙醚（TMDAE）（四核二聚体8和单体10）、N,N,N',N'',N''-五甲基二亚乙基三胺（PMDETA）（四核二聚体7）、三[2-二甲基（氨基）乙基]胺（MeTREN）（四核二聚体9）和三{2-(2-甲氧基乙氧基)乙基}胺（TMEEA）（单体11）。还通过氢和碳核磁共振光谱以及扩散排序核磁共振光谱在溶液中对这些配合物进行了研究。
