탈할로겐화수소 반응으로 유기할로겐 화합물에 실란을 결합시키는 방법{DEHYDROHALOGENATIVE COUPLING REACTION OF ALKYL HALIDES WITH SILANE}A method of coupling silane to an organohalogen compound by a dehalogenation reaction. {DEHYDROHALOGENATIVE COUPLING REACTION OF ALKYL HALIDES WITH SILANE}

본 발명은 3차 유기 포스핀 촉매 하에 수소-규소 결합을 갖는 클로로실란 화합물과 유기 할로겐 화합물을 탈할로겐화수소반응에 의해 결합시키는 방법에 관한 것이다.The present invention relates to a method of combining an organic halogen compound with a chlorosilane compound having a hydrogen-silicon bond under a tertiary organic phosphine catalyst by a dehalogenation reaction.

1968년, 벤케서와 스미스는 처음으로 트리클로로실란과 트리알킬아민의 1:1 혼합물로 사염화탄소를 클로로포름으로 환원시키는 반응을 보고하였다 (Benkeser, R.A.; Smith, W. E.J. Am. Chem. Soc.1968, 90, 5307). 이 환원반응은 트리클로로실란과 사염화탄소 및 트리알킬아민이 반응하여 염화수소가 빠지는 반응을 일으켜 트리클로로메틸트리클로로실란이 형성되었다가 트리알킬암모늄 클로라이드에 의해 클로로포름과 테트라클로로실란으로 분해된다고 보고되었다. 벤케서와 그의 공동연구자들은 1969년에 다시 벤질 클로라이드와 1,1,1-트리클로로에탄이 트리클로로실란과 트리알킬아민의 1:1 혼합물과 반응하여 탈염화수소반응으로 클로로 대신 트리클로로실릴기가 치환된 화합물이 생성된다고 보고하였다 (Benkeser, R.A.; Gaul, J. M.; Smith, W.E.,J. Am. Chem. Soc. 1969, 91, 3666).In 1968, Benkeser and Smith reported for the first time the reaction of reducing carbon tetrachloride to chloroform with a 1: 1 mixture of trichlorosilane and trialkylamine (Benkeser, RA; Smith, WE J. Am. Chem. Soc. 1968 , 90, 5307). It has been reported that trichlorosilane reacts with carbon tetrachloride and trialkylamine to release hydrogen chloride, forming trichloromethyltrichlorosilane, which is then decomposed into trichloroammonium chloride by chloroform and tetrachlorosilane. Benkeser and his co-workers reinvented the reaction of benzyl chloride and 1,1,1-trichloroethane with a 1: 1 mixture of trichlorosilane and trialkylamine in 1969, replacing trichlorosilyl groups with dehydrochlorination. Reported compounds (Benkeser, RA; Gaul, JM; Smith, WE, J. Am. Chem. Soc . 1969, 91, 3666).

1975년에는 일본의 후루야와 수카와가 알릴클로라이드에 트리클로로실란과 트리알킬아민의 1:1 혼합물을 반응시키는데 구리염화물을 촉매로 사용하면 높은 수율로 알릴트리클로로실란이 얻어진다고 보고하였다 (Furuya, N.; Sukawa, T.,J. Organometal. Chem.1985, 96, C1).In 1975, Furuya and Sukawa of Japan reported a 1: 1 mixture of trichlorosilane and trialkylamine with allyl chloride, and copper chloride was used as a catalyst to obtain allyl trichlorosilane in high yield (Furuya, N .; Sukawa, T., J. Organometal.Chem. 1985, 96, C1).

최근, 프랑스의 꼬류와 그의 공동연구자들은 과량의 트리부틸아민을 사용하여 클로로포름과 트리클로로실란을 반응시켜 비스(트리클로로실릴)메탄과 트리스(트리클로로실릴)메탄을 합성하였다고 보고하였다 (Corriur, R. J. P.: Granier, M.; Lanneau, G.F.J. Organometal. Chem.1998, 562, 79).Recently, French pods and their co-workers reported the synthesis of bis (trichlorosilyl) methane and tris (trichlorosilyl) methane by reacting chloroform with trichlorosilane using excess tributylamine (Corriur, RJP Granier, M .; Lanneau, GF J. Organometal.Chem. 1998, 562, 79).

상기 종래기술에 따르면 클로로메틸기를 갖는 유기규소화합물이 유기염기 존재 하에서 트리클로로실란과 반응하여 탈염화수소반응으로 결합한다는 것을 알 수 있다.According to the prior art, it can be seen that the organosilicon compound having a chloromethyl group is reacted with trichlorosilane in the presence of an organic base to bind with a dehydrochlorination reaction.

이 탈염화수소반응은 탄소와 규소의 결합을 형성시키는 새로운 반응으로 유기규소화합물을 합성하는데 매우 유용한 반응이다. 그러나 벤질클로라이드나 알릴클로라이드와 같은 활성화된 염화알칸이 트리클로로실란과 탈염화수소반응으로 결합한다는 보고는 있으나 단순한 염화알칸이 이와 같은 반응을 한다는 것은 이제까지 보고된 바 없다. 이 반응에서도 강한 염기성을 갖는 3차 아민이 과량으로 사용되므로 이 반응에서 아민을 촉매라고 하기보다는 염화수소를 잡아주는 반응물질이라고 보는 것이 타당하다. 이것은 염화수소를 중화하고 아민을 회수하는데 많은 비용이 들어 공업적으로 많이 활용되기 어렵다. 따라서, 아민을 소량 사용하여 반응시키거나 다른 촉매를 찾는 것이 이 공정의 경제성을 높이는 관건이 된다.This dehydrochlorination reaction is a new reaction that forms a bond between carbon and silicon and is very useful for synthesizing organosilicon compounds. However, although it has been reported that activated alkane chlorides such as benzyl chloride and allyl chloride are combined with trichlorosilane in a dehydrochlorination reaction, it has never been reported that simple alkane chloride reacts as such. In this reaction, since the tertiary amine having a strong basicity is used in excess, it is reasonable to regard the amine as a reactant that catches hydrogen chloride rather than a catalyst in this reaction. It is expensive to neutralize hydrogen chloride and recover amines, making it difficult for industrial use. Therefore, using a small amount of amine to react or finding another catalyst is the key to increasing the economics of this process.

본 발명자들은 상기한 종래기술의 문제점을 해결하고자 연구하던 중, 3차 유기 포스핀을 촉매로 사용하여 수소-규소 결합을 갖는 화학식 1의 클로로실란 화합물과 화학식 2의 유기 할로겐 화합물을 탈할로겐화수소 반응으로 결합시킴으로써 화학식 3의 화합물들을 제조할 수 있음을 발견하였다. 이를 다음 반응식 1에 나타내었다.The present inventors have been studying to solve the above problems of the prior art, using a tertiary organic phosphine as a catalyst to dehydrohalogenation reaction of the chlorosilane compound of Formula 1 and the organic halogen compound of Formula 2 having a hydrogen-silicon bond It was found that the compounds of the formula 3 can be prepared by binding to. This is shown in Scheme 1 below.

즉, 본 발명자들은 유기 아민보다 염기성이 낮은 3차 유기 포스핀 화합물을 촉매로 사용하여 벤질클로라이드나 알릴클로라이드와 같은 활성화된 염화알칸 뿐만 아니라 단순한 유기 할로겐 화합물과 할로겐이 치환된 알킬기를 갖는 유기규소 화합물도 Si-H 결합을 갖는 실란을 탈할로겐화수소 반응으로 결합시키는 방법을 발견하였다. 압력에 견디는 반응조에 화학식 1의 화합물과 화학식 2의 유기 할로겐 화합물 그리고 촉매로 3차 유기 포스핀 화합물을 화학식 2의 화합물에 대해 1 내지 100몰%, 바람직하게는 5 내지 20몰% 정도 넣고 섭씨 10-200℃, 바람직하게는 100 - 200℃로 가열시켜 화학식 3과 같은 유기실란을 합성하였다 (반응식 1 참조).That is, the present inventors use a tertiary organic phosphine compound having a lower basicity than an organic amine as a catalyst, and an organosilicon compound having a simple organic halogen compound and a halogen-substituted alkyl group as well as an activated alkane chloride such as benzyl chloride or allyl chloride.
