Usage

Uses

Different sources of media describe the Uses of 3768-58-9 differently. You can refer to the following data:
1. Bis(dimethylamino)dimethylsilane is used in the chemical vapor deposition of silicon nitride films, and also the atomic layer deposition of SiNxCy dielectric sealing layers using plasma-enhanced atomic layer deposition (PE-ALD). It is also used as a reagent for silylation.
2. Bis(dimethylamino)-dimethyl silane has been used to silanize pH-sensitive microelectrodes, used to measure the membrane potential in oocytes, in an experimental procedure aimed towards cloning and characterizing human electrogenic Na+-cotransporter isoform (hhNBC). It is also used for microelectrode measurements, in a study conducted to measure carbon dioxide transport through membranes. It is also used in electronic film deposition.

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.

Complexation and Exchange Reactions of some Dimethylamino-substituted Group 4 Compounds

Reactions of CH2(NMe2)2, (1), SiMe2(NMe2)2, (2), (cp=η-cyclopentadienyl), (3), and , (4), with covalent metal halides MCl4 (M=Ti,Zr,Si,Ge,or Sn) and MCl3 (M=Ti,V,or Cr) fall into two categories: (a) N-donor chelation leading to complex formation and (b) halide-NMe2 exchange.Compound (1) gives 1:1 complexes with MCl4 (M=Ti or Sn) and 2:1 complex with VCl3.Compound (2) provides 1:1 complexes with MCl4 (M=Ti,Zr,Hf, or Sn).The decomposition of TiCl4*SiMe2(NMe2)2 --> invariably occurs in both the solid state and solution.There is no reaction of (2) with metal(III) chlorides.With MCl4 (M=Si or Ge 'scrambling' reactions involving halide-NMe2 exchange occur and these have been monitored by 1H n.m.r. spectroscopy.Reactions of (3) and (4) with MCl4 (M=Si,Ge,Sn,Ti,Zr,or Hf) consistently feature halide-NMe2 exchange rather than adduct formation.All complexes have been characterised by analytical and spectroscopic (1H n.m.r. and i.r.) investigations.
