Abstract
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 Me 2 Si(NR 1 R 2 ) 2 and Me 2 Si(NR 3 R 4 ) 2 containing different amino moieties leads to the formation of mixed diaminosilanes Me 2 Si(NR 1 R 2 )(NR 3 R 4 ) in most cases.
期刊介绍：
This journal is committed to the publication of short communications, original research, and review articles within the field of main group metal and semi-metal chemistry, Main Group Metal Chemistry is an open-access, peer-reviewed journal that publishes in ongoing way. Papers addressing the theoretical, spectroscopic, mechanistic and synthetic aspects of inorganic, coordination and organometallic main group metal and semi-metal compounds, including zinc, cadmium and mercury are welcome. The journal also publishes studies relating to environmental aspects of these metals, their toxicology, release pathways and fate. Articles on the applications of main group metal chemistry, including in the fields of polymer chemistry, agriculture, electronics and catalysis, are also accepted.
