SILYL SUBSTITUTED 1,4-DISILACYCLOHEXANE DERIVATIVES AND PREPARATION METHOD THEREOF

The present invention relates to novel 1,4-disilacyclohexane derivatives and a preparation method thereof. More particularly, the invention provides a method for preparing 1,4-disilacyclohexane derivatives with a hexagonal ring structure at high yield through double silylation of an organosilane compound and a vinyl silane compound having an unsaturated double bond using quaternary organophosphonium salts as a catalyst. According to the present invention, tris(silyl)ethanes having three silyl groups in one molecule can be prepared at the same time and the catalyst can be recovered after reaction. Thus, the method is economical and enables mass-production of 1,4-disilacyclohexane derivatives and tris(silyl)ethanes which are precursors of organic-inorganic hybrid materials.

Synthesis and Characterization of Simple α-Sila- and α,ω-Disilaalkanes: Precursors for the CVD Production of Amorphous Silicon a-SiC:H

Preparative methods have been explored for the synthesis of small, volatile polysilaalkanes, which could serve as starting materials for the production of amorphous silicon a-SiC:H.High yield pathways have been developed for H3SiCH2CH2SiH3 and H3SiCH2CH2CH2SiH3.These compounds can be converted into symmetrically halogen-functional derivatives through the reactions with SnCl4 or Br2.The homologous H3SiCH2CH2SiH2CH3 has also been prepared and halogenated, starting from the corresponding vinylsilane via the hydrosilylation route.Allylsilanes were the source of the synthesis of H3SiCH2CH=CH2, CH3SiH2CH2CH=CH2, SiH2(CH2CH=CH2)2, SiH2(CH2CH2CH2SiH3)2, or HSi(CH2CH2CH2SiH3)3.Methylated derivatives are also available. - Some physical and spectroscopic properties of the new compounds have been investigated.In particular, NMR data were collected and used for an assessment of structure and isomerism. - Key words: Disilaalkanes, Silanes, Amorphous Silicon, Hydrosilylation
