Description
본 발명은 올레핀 화합물의 중합반응에 유용한 촉매로 사용될 수 있는 신규한 (풀루오레닐알킬)실란 화합물 및 이들의 제조방법에 관한 것이다.The present invention relates to novel (puluorenylalkyl) silane compounds that can be used as catalysts useful in the polymerization of olefin compounds and methods for their preparation.
1877년 프리델과 크라프트가 벤젠과 알킬할라이드를 알루미늄클로라이드 존재하에 반응시켜 알킬기가 첨가된 알킬벤젠을 제조하는 방법을 처음으로 발표하였으며, 그 후 이를 프리델-크라프트 반응이라 한다. 이 반응은 루이스산 존재하에 알킬기, 아실기, 아릴기 등을 벤젠 고리에 도입하는 반응으로서, 이는 산업적인 유기화합물의 제조공정에 매우 유용하게 활용되고 있다(R. M. Roberts and A. A. Khalaf, Friedel-Crafts Alkylation Chemistry, Marcel Dekker, Inc., NY, 1984).In 1877 Friedel and Kraft first presented a process for the production of alkylbenzenes to which alkyl groups were added by reacting benzene and alkyl halides in the presence of aluminum chloride, which is called the Friedel-Crafts reaction. This reaction introduces alkyl, acyl and aryl groups into the benzene ring in the presence of Lewis acid, which is very useful for the manufacturing process of industrial organic compounds (RM Roberts and AA Khalaf, Friedel-Crafts Alkylation). Chemistry, Marcel Dekker, Inc., NY, 1984).
본 발명자들은 벤젠 유도체들과 (폴리클로로알킬)실란 화합물들을 알루미늄클로라이드 등의 루이스산 촉매하에서 프리델-크라프트 알킬화 반응으로 알킬기에 치환된 염소의 숫자만큼 벤젠 유도체를 치환시켜 (폴리아릴알킬)실란 화합물을 제조할 수 있음을 발견하고 이를 출원한 바 있다(대한민국 특허출원 제 96-77559 호, 출원일자 : 1996년 12월 30일 ).The present inventors have substituted (polyarylalkyl) silane compounds by substituting benzene derivatives with the number of chlorine substituted by alkyl groups by Friedel-Craft alkylation reactions of benzene derivatives and (polychloroalkyl) silane compounds under Lewis acid catalysts such as aluminum chloride. It was found that it can be manufactured and has filed it (Korean Patent Application No. 96-77559, filed December 30, 1996).
또한, 본 발명자들은 바이페닐 유도체와 디클로로알킬실란 화합물의 프리텔-크라프트 알킬화 반응을 연구하던중 알킬화 반응으로 두개의 페닐기를 연결하는 5각형의 고리화가 일어나 풀루오렌 고리가 치환된 실란 화합물을 제조할 수 있다는 것을 발견하고 이를 출원한 바 있다(대한민국 특허출원 제 97-9346 호, 출원일자 : 1997년 3월 19일 ).In addition, the present inventors, while studying the pretel-craft alkylation reaction of a biphenyl derivative and a dichloroalkylsilane compound, a pentagonal cyclization that connects two phenyl groups by an alkylation reaction occurs to prepare a silane compound substituted with a fullerene ring. It was found and filed (Korean Patent Application No. 97-9346, filed March 19, 1997).
풀루오렌 고리가 치환된 실란 화합물은 상기 본 발명자들이 출원한 한국특허출원 제 97-9346 호에서와 같이 올레핀 중합반응의 촉매로 주목을 받고 있는 풀루오레닐 메탈로센 화합물[ Organometallics, 14, 789 (1995), J. Organomet. Chem., 508, 91 (1996) ]을 제조하는데 유용한 화합물이다.The silane compound substituted with a fullerene ring is a pulleylenyl metallocene compound that is attracting attention as a catalyst for olefin polymerization as described in Korean Patent Application No. 97-9346 filed by the present inventors [Organometallics, 14, 789 ( 1995), J. Organomet. Chem., 508, 91 (1996)] are useful compounds.
한편, 풀루오렌 유도체들은 2번과 7번 탄소 위치에 할로겐을 도입한 후에 아연 금속을 이용하여 할로겐을 제거하고 폴리풀루오렌을 제조하여 광발광 또는 전기발광 재료로 사용될 수 있다고 알려졌다[ J. Am. Chem. Soc. 118, 7416 (1996) ]. 풀루오렌의 9번 탄소에 알킬기가 도입된 유도체를 제조하기 위해서는 알킬리튬과 같은 시약을 사용하는 것이 일반적이다. 그러나 알킬리튬은 고가일 뿐만 아니라 사용시 위험이 따르므로 경제적인 방법이라 할 수 없다.On the other hand, it is known that pullulene derivatives can be used as photoluminescent or electroluminescent materials by introducing halogen at the carbon positions 2 and 7 and then removing halogen using zinc metal and preparing polypululene [J. Am. Chem. Soc. 118, 7416 (1996). It is common to use a reagent such as alkyllithium to prepare a derivative in which an alkyl group is introduced at the carbon number 9 of pullulene. However, alkyllithium is not only economical because it is expensive and risks in use.

The reaction was extracted with nucleic acid and the filtrate was distilled at atmospheric pressure to remove hexane and distilled under vacuum to yield 0.20 g of 9-methyl-9 (2-methyldichlorosilylethyl) pullulene.
