General Description

BIS(ETHYLAMINO)DIMETHYLSILANE, also known as N,N-Bis(ethylamino)dimethylsilane, is a chemical compound with the formula (C2H5)2NSi(CH3)2. It is a colorless liquid with a faint odor and is used as a reagent in various chemical reactions, particularly in the synthesis of silane polymers and other silicon-containing compounds. BIS(ETHYLAMINO)DIMETHYLSILANE is also utilized in the manufacturing of semiconductor and microelectronic devices, serving as a precursor to various silicon-based materials. It is highly flammable and should be handled with care and stored in a cool, dry place away from sources of heat and ignition.

Insertion of phenyl isocyanate into monoand diaminosilanes

The aminosilanes MenSi(NRR')4-n (n = 2,3) with NRR' = ethylamino (NHEt), n-propylamino (NHnPr), sec-butylamino (NHsBu), n-octylamino (NHnOct), n-dodecylamino (NHnDodec), allylamino (NHAll), tert-butylamino (NHtBu), diethylamino (NEt2), and anilino (NHPh) were synthesized and their reactions with phenyl isocyanate were studied. In all cases of these silanes Me3SiNRR' and Me2Si(NRR')2 formal insertion of the -NCO group into their Si-N bonds was observed, i.e. formation of products with Si-N (rather than Si-O) bonds was found. In some cases, the products could be crystallized and their molecular structures have been elucidated with single-crystal X-ray diffraction analyses.

Synthesis and characterisation of novel zirconium(IV) derivatives containing the bis-amido ligand SiMe2(NRR′)2

The silicon compounds SiMe2(NRR′)2 [NRR′ = NMe2 (1), NEt2 (2), NC4H8 (3), NHEt (4), NHiPr (5), NHtBu (6), NMeBu (7)] have been synthesised via aminolysis of the dichloro species SiMe2Cl 2 and their ligating ability has been investigated towards zirconium(IV). The dimer zirconium compound {Zr[(NiPr) 2SiMe2]2}2 (8) has been synthesised by reacting ZrCl4 with the lithium salt Li2[(N iPr)2SiMe2] and its molecular structure has been determined in the solid state by X-ray diffraction analysis. The reaction of ZrCl4 with SiMe2(NRR′)2 yields the Lewis adducts ZrCl4[(NRR′)2SiMe2] [NRR′ = NMe2 (10), NC4H8 (11), NHEt (12), NHiPr (13), NHtBu (14), NMeBu (15)]. On the other hand, the mixed amido derivative Zr(NMe2)3(NHMe)[(N′Bu) SiMe2(NH′Bu)] (9) has been obtained from the reaction of Zr(NMe2)4 with SiMe2(NHtBu) 2. The solution molecular structure and dynamics of the zirconium derivatives have been elucidated by 1D and 2D multinuclear NMR spectroscopy.
