Abstract
Transamination reactions of two different aminosilanes (trimethyl(tert-butylamino)silane and dimethyl(diamino)silane) with amines (diethylamine, pyrrolidine, tert-butylamine, iso-propylamine, and n-propylamine) are studied. For trimethyl(organoamino)silanes, the reaction of trimethyl(iso-propylamino)- or trimethyl(diethylamino)silane as aminosilanes and aniline or pyrrolidine are good starting materials to produce trimethyl(anilino)- and trimethyl(pyrrolidino)silane. The investigated equilibrium constants of the reactions of monoaminosilanes show a good correlation with quantum chemically calculated values. The reaction of two different diaminosilanes Me2Si(NR1R2)2 and Me2Si(NR3R4)2 containing different amino moieties leads to the formation of mixed diaminosilanes Me2Si(NR1R2)(NR3R4) in most cases.
摘要
研究了两种不同氨基硅烷(三甲基(叔丁氨基)硅烷和二甲基(二氨基)硅烷)与胺(二乙胺、吡咯烷、叔丁胺、异丙胺和正丙胺)的转胺反应。对于三甲基(有机氨基)硅烷,三甲基(异丙基氨基)硅烷或三甲基(二乙基氨基)硅烷作为氨基硅烷与苯胺或吡咯烷反应是生成三甲基(苯胺基)硅烷和三甲基(吡咯烷基)硅烷的良好起始原料。所研究的单氨基硅烷反应平衡常数与量子化学计算值具有良好的相关性。含有不同氨基的两种不同二氨基硅烷 Me2Si(NR1R2)2 和 Me2Si(NR3R4)2 的反应在大多数情况下会形成混合二氨基硅烷 Me2Si(NR1R2)(NR3R4)。
