  • Publication number: 20110105777
    Abstract: 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.

    Abstract: The present invention relates to a preparation method for a linear or cyclic trisilaalkane which is a substance useful in the preparation of polycarbosilane and silicon carbide precursors. Linear or cyclic trisilaalkane and organic trichlorosilane derivatives can be synthesized simultaneously and in high yield by reacting bis(chlorosily)methane having a Si—H bond, either alone or together with an organic chloride, using a quaternary organic phosphonium salt compound as a catalyst. Further, since the catalyst can be recovered after use, the present invention is very economical and is thus effective for mass-producing precursors for organic/inorganic hybrid substances.

    Abstract: A polycyclic fused ring type ?-conjugated organic material (VIIa, VIIb, VIIc, VIId) is obtained in the following manner. That is, as shown in Scheme 1 below, a starting material (I) is dimetalated with an organometallic base. The starting material (I) thus dimetalated is trapped with an organosilicon reagent (i: (1) n-BuLi or t-BuLi; (2) HMe2SiCl). As a result, an intermediate is obtained. Thereafter, the intermediate is allowed to react with a metal reductant. This causes an intramolecular reductive cyclization reaction to proceed. As a result, a dianion intermediate is produced. The dianion intermediate is trapped with an electrophile (ii: (1) LiNaph, THF, rt, 5 min; (2) electrophile or NH4Cl) In this way, the polycyclic fused ring type ?-conjugated organic material is obtained.
