Provided is an organic chlorohydrosilane, a useful starting material for preparing silicon polymers and a method for preparing the same. More particularly, the present invention enables the synthesis of various novel organic chlorohydrosilanes in high yield by an exchange reaction between an Si—H bond of a chlorosilane which can be obtained in an inexpensive and easy manner and an Si—Cl bond of an another organic chlorosilane using a quaternary organic phosphonium salt compound as a catalyst. Since the catalyst can be recovered after its use and reused, the present invention is very economical and thus effective for mass-producing silicon raw materials.

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.
