1,2-DICHLOROTETRAMETHYLDISILANE Chemical Properties,Uses,Production

Description

1,2-DICHLOROTETRAMETHYLDISILANE is a kind of widely used organic silicon intermediates and usually be used as organic silicon blocking agent in the synthesis,such as,Si-Si Compounds; Dichlorosilanes (for Polysilanes); Electroluminescence; Functional Materials; Monochlorosilanes; Reagent for High-Performance Polymer Research; Si (Classes of Silicon Compounds); Si-Cl Compounds; Silicon Compounds (for Synthesis); Synthetic Organic Chemistry; Precursors by Metal; Vapor Deposition Precursors.

Uses

1,2-DICHLOROTETRAMETHYLDISILANE is used as an intermediate for preparing other organical compounds. It is also used in aqueous polymer preparation as well as a laboratory reagent. 1,2-Dihydroxy-tetramethyldisilane has been synthesized by hydrolysis of 1,2-dichloro-tetramethyldisilane and characterized by IR, NMR, MS and X-ray structure analysis.

Synthesis

Tetramethyldisilane (XIV, 0.3 mmol), excess MeSiC (IV, 1.7 mmol), diglyme (0.35 ml) and n-Bu4PCI (0.02 mmol) as catalyst were placed in an NMR tube that was cooled to -196 °C (liquid nitrogen). After evacuation in vacuo the NMR tube was sealed, warmed to r.t. and the reaction course was monitored by NMR spectroscopy. Me2SiHCI III was not detected at r.t. but the disilane was chlorinated to give disilane XV (12%). Reduction of MeSiC (H-transfer from disilane XIV) yielded V in small amounts (1.2%) while target product VI was formed in nearly 40% yield (80 °C/+4 h). At 120 °C (additional 19 h) disilane XV was reduced by about a half (1 1.9% → 6.7%) to form dimethyldichlorosilane II in 13.8% yield. The catalyst remained unreacted as shown by31P-NMR spectroscopy.
