Usage

General Description

1,1,2-trichloro-1,2,2-trimethyldisilane, also known as Trichlorotrimethylsilane, is a colorless, volatile liquid with a pungent odor. It is a chlorosilane compound that is commonly used as a reagent in organic synthesis and as a silylating agent in analytical chemistry. It is highly reactive and is often used in the protection of hydroxyl and amine groups in organic molecules. 1,1,2-trichloro-1,2,2-trimethyldisilane is also used in the production of silicone polymers and as a precursor for the synthesis of other organosilicon compounds. It is important to handle this chemical with caution, as it can be hazardous if not properly managed and can cause severe skin and eye irritation.

AEQUILIBRIERUNGSREAKTIONEN AN DISILANEN

Redistribution reactions of Si2Me6 and Si2Cl6 and of Si2Me2Cl4 and Si2Me2H4 are discussed.While the high temperature necessary for the exchange between methyl and chlorine leads to rupture of the silicon-silicon bond in the case of the Si2Me6/Si2Cl6 system, redistribution of chlorine and hydrogen proceeds at room temperature with AlCl3 as catalyst.The reaction between Si2Me2Cl4 and Si2Me2H4 at 90 deg C is examined in detail by 1H NMR spectroscopy.This reaction is a useful route for preparation of the new compounds Me2Si2ClxH4-x (x=1-3). 1H NMR, 13C NMR, 29Si NMR, IR and Raman spectroscopic data of the partly unknown 1,2-dimethylchlorodisilanes are reported.

The synthesis of novel chlorosilyl and chlorogermyl mercurials with some of their chemical reactions

When a mercury alkyl is irradiated in the presence of trichlorosilane, bis(trichlorosilyl)mercury, a white crystalline solid, and the alkane are formed. In a similar reaction with methyldichlorosilane, bis(methyldichlorosilyl)mercury is a product. With trichlorogermane as a reactant a similar light-induced reaction produces bis(trichlorogermyl)mercury. These novel mercurials react with compounds possessing a silicon-hydrogen bond to form disilanes. Preparations are described for methylpentachlorodisilane, 1,1-dimethyltetrachlorodisilane, 1,2-dimethyltetrachlorodisilane, 1,1,1,-trimethyltrichlorodisilane, 1,1,2-trimethyltrichlorodisilane, 1,1,1,2-tetramethyldichlorodisilane, 1,1,2,2-tetramethyldichlorodisilane, pentamethylchlorodisilane, trichlorosilyltrichlorogermane, and trimethylsilylmethyltrichlorogermane using various modifications of this reaction. Syntheses have been devised for the mercurials, bis(trichlorosilyl)mercury, bis(methyldichlorosilyl)mercury, bis(trichlorogermyl)mercury, and (trimethylsilylmethyl)trichlorogermylmercury. Bis(dimethylchlorosilyl)mercury is formed at low temperatures but decomposes at temperatures above -79°. Bis(trichlorosilyl)mercury also reacts with dimanganese decacarbonyl to form trichlorosilylmanganese pentacarbonyl.

Atrane Analogous Compounds of the Type (I)

Heterocyclic cage compounds of type I (compounds 8 - 10) have been prepared by condensation reactions of 1,2,2-trifunctional disilanes Me(R)XSiSiMeX2 (R = Me, Ph, OEt; X = NMe2, OEt) with triethanolamine using the "Dilution Principle".The starting compounds are obtained by Si - Me cleavage of Si2Me6 with acetylchloride/AlCl3 followed by either aminolysis with HNMe2 or alcoholysis with EtOH. 1H NMR spectra indicate N -> Si(1) intraction with the more acidic Si atom in 8 and 9.This result is proved by the X-ray structure analysis of 8 (monoclinic, P 21/c; a = 7.088(2), b = 15.070(4), c = 12.701(4) Angstroem, β = 104.96(2) at -130 deg C, Z = 4); the Si(1) *** N distance is found to be 2.768 Angstroem, connected with a significant angular distortion of the tetrahedral coordination around Si(1) towards a trigonal bipyramid.In compound 10, too, N -> Si(1) coordination is observed at room temperature in spite of almost equal acidity for both Si atoms.This can be explained by the preference of 5- over 6-membered chelating ring systems.At higher temperatures the 1H NMR spectra show a fluctuation of the N-donor between the two Si centres. - Key words: Silatranes, Transanular N -> Si-Interactions, NMR Spectra, X-Ray
