This patent application claims the benefit of priority from Korean Patent application No. 10-2009-0063616, filed on Jul. 13, 2009 in the Korean Intellectual Property Office (KIPO), the contents of which are incorporated herein by reference.
The present invention relates to an organic chlorohydrosilane and a method for preparing the same, and more particularly, to a method for synthesizing various novel organic chlorohydrosilanes in high yield by an exchange reaction between an Si—H bond of a chlorosilane and an Si—Cl bond of an another organic chlorosilane using a quaternary organic phosphonium salt compound as a catalyst.
Recently, the present inventors have reported a method in which an alkyl chloride having a C—Cl bond and a trichlorosilane (HSiCl3) having an Si—H bond were reacted using a tetraalkylphosphonium chloride compound as a catalyst to form a silicon-carbon (Si—C) bond, while removing hydrogen chloride upon producing it by detaching chlorine from the alkyl chloride and hydrogen from the trichlorosilane (HSiCl3), to thus synthesize various organic silicon compounds (Y. S. Cho; S-H. Kang; J. S. Han; B. R. Yoo; II Nam Jung; J. Am. Chem. Soc., 123, 2001, 5583; I. N. Jung et al, U.S. Pat. No. 6,392,077). This dehydrochlorination is a novel method for forming a silicon-carbon bond, which is very useful for synthesizing various novel organic silicon compounds.
Organic chlorides like trichlorosilanes used for the dehydrochlorination can be reacted with alkyl chlorides that do not have a strong activity, cyclic alkyl chlorides, and tertiary alkyl chlorides, as well as alkyl chlorides in which a chlorine is bonded to a carbon having a strong activity, such as benzyl chloride or allyl chloride, to thus synthesize organic silicon compounds in high yield.
In the Korean Patent Number 10-0487904 (Apr. 27, 2005), the present inventors have disclosed that when ketones or aldehydes are reacted with a trichlorosilane (HSiCl3) using a tetraalkylphosphonium chloride compound catalyst, organic trichlorosilanes in which trichlorosilane is introduced into the site of oxygen are obtained.
In addition, the present inventors have disclosed in the Korean Patent Number 10-0491960 (May 30, 2005) that when alkenes are reacted with a trichlorosilane using a quaternary organic phosphonium salt as a catalyst, bissilylalkane compounds into which two silyl groups are introduced to the carbon-carbon double bond through silylation can be synthesized in high yield.
In this way, the method using a tetraalkylphosphonium chloride compound catalyst can prepare silane compounds having various organic groups and thus has enabled the manufacture of new products through the supply of new raw materials for the silicone industry or the manufacture of various products through the modification of existing products.
However, there are limitations that silane compounds prepared in this way have trichlorosilyl groups at one side or both sides of a molecule and have multiple Si—Cl bonds in one molecule, and are not suitable for manufacturing silicone oil or rubber which are most commonly used in the silicone market. Namely, raw materials which can be used for manufacturing silicone oil or rubber need to have two organic groups and two Si—Cl bonds in one silicon atom. Therefore, the exchange reaction of an Si—Cl bond for an Si—H bond can reduce the number of Si—Cl bonds and an Si—H bond can be added to organic groups having a double bond or a triple bond through hydrosilylation and it enables the preparation of raw materials having various organic groups. Therefore, the exchange reaction of an Si—Cl bond for an Si—H bond is very significant.
Meanwhile, in the exchange reaction of an Si—Cl bond and an Si—H bond, Lewis acids such as aluminum chloride and boron chloride are known to have a catalytic effect for the redistribution reaction of chlorosilanes. Organic compounds such as tertiary amines, quaternary ammonium chlorides, nitrile compounds, and organic phosphine compounds, are known to play a role as a catalyst in the following reactions of the redistribution of trichlorosilane (HSiCl3) to dichlorosilane and the preparation of mono(chloro)silane.
Union Carbide Corporation in the U.S. have reported that Amberyst (manufactured by Rohm and Haas company in the U.S.) in which amines or ammonium salts are immobilized on an ion exchange resin is a good catalyst in this reaction. With this, a matter of separating reaction products from catalysts after reaction was solved.
However, Amberyst immobilized on an ion exchange resin has several disadvantages. Since it is a porous resin, it absorbs moisture and is susceptible to swelling. In addition, it is degraded easily under acidic conditions because amines or ammonium salts are substituted at the benzyl sites. Therefore, the present inventors have developed a new immobilized catalyst by substituting amines or ammonium salts on a silicone resin and disclosed it in the U.S. Pat. No. 4,613,491 and U.S. Pat. No. 4,701,430.
However, among the exchange reactions of Si—H bonds and Si—Cl bonds, few reactions which can be applied to organic chlorohydrosilanes which are substituted with alkyl groups have been reported. In 1947, Whitmore and his colleagues reported the reaction for the first time (F. C. Whitmore; E. W. Pietrusza; L. H. Sommer, J. Am. Chem. Soc., 69, 1947, 2108). The catalyst used for the following reaction was aluminum chloride (AlCl3).
In 1957, Dolgov and his colleagues in Russia reported that they redistributed ethyldichlorosilane into ethylchlorosilane and ethyltrichlorosilane in the presence of aluminum chloride catalyst (B. N. Dolgov; S. N. Borisov; M. G. Voronkov, Zhur. Obschei. Khim., 27, 1957, 2062). However, since the redistribution reaction using aluminum chloride as a catalyst requires the reaction temperatures as high as 150 to 400° C., it lacks practicality.
Bailey and Wagner reported that they redistributed ethyldichlorosilanes or phenyldichlorosilanes using adiponitrile as a catalyst at the temperature of 150 to 200° C. (D. L. Bailey and G. H. Wagner).
The present inventors intend to solve the limitations of the related art for preparing an organic chlorohydrosilane, a useful starting material for manufacturing a variety of silicone oil or rubber.
Therefore, the present inventors used a quaternary organic phosphonium salt compound which has never been used for a catalyst and inexpensive chlorosilanes having an Si—H bond and exchanged one or two Si—Cl bonds among three Si—Cl bonds in organic trichlorosilanes for Si—H bond(s), thereby preparing organic chlorohydrosilanes in high yield in which both an Si—Cl bond which can be hydrolyzed and then polymerized and an Si—Cl bond which can react with a unsaturated organic compound through hydrosilylation so as to incorporate a new organic group are included within one molecule.
Therefore, the present invention is to provide an organic chlorohydrosilane which has both an Si—Cl bond and an Si—H bond within one molecule.
The present invention is also to provide a method for preparing the organic chlorohydrosilane.
The present invention can synthesize a new organic chlorohydrosilane in high yield which includes both an Si—H bond and an Si—Cl bond by using a quaternary organic phosphonium salt 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. In addition, since using the catalyst enables the reaction at a comparatively low temperature ranging from room temperature to about 200° C. or lower, the present invention is economical.
