Description

亚乙基桥联取代茚芴锆化合物及其制备方法和应用
技术领域
本发明涉及一类茂金属化合物及其制备方法,尤其涉及桥联茂金属络合物的制备及其在烯烃均聚中的应用。 
背景技术
上世纪50年代初,Ziegler-Natta催化剂(J.Am.Chem.Soc.,1957,79,2975)应用于烯烃聚合的成功,使得金属有机化合物化学得到迅猛的发展。80年代初,Sinn(Angew.Chem.Int.Ed.Engl.,1980,92,396)和Kaminsky(Macromol.Chem.,Rapid Commun.,1983,4,417)等人发现了茂金属络合物和MAO组成的均相催化烯烃聚合体系,与传统的Ziegler-Natta催化剂相比,茂金属催化剂活性中心的电负性和空间环境可以有较大的变化,这就使生成的高分子链的组成和结构高度可控。即使是茂金属络合物结构上的微小变化,都可能产生性能完全不同的聚合物。 
上世纪九十年代中期,Rieger(Organometallics,1994,13,647)和Chien(J.Organomet.Chem.,1995,497,1)等课题组报道了一系列含不同桥基的茚芴锆金属络合物:X(Ind)(Flu)ZrCl2(X=CH2CH2,Me2Si,PhCHCH2,etc.),用于催化丙烯聚合,具有较高的催化活性和中等的等规选择性。此后,Alt课题组(欧洲公开专利,1998,EP 0853086)和Siedle等人(J.Mol.Catal.A:Chem.,2003,191,167)也对这类桥联型茚芴金属络合物进行了一些研究,在茚3-位引入各种烷基取代基,用于催化丙烯聚合,以得到具有较高等规立构规整度的等规聚丙烯;或用于催化乙烯聚合,得到较高分子量的聚乙烯。但关于这类C1-对称桥联型茚芴金属络合物的研究,含芳基取代的络合物很少,带芳基的大位阻3-取代茚乙基芴锆金属络合物的合成和应用未见报道。 
使用茂金属络合物不仅可以催化烯烃聚合得到高分子量的聚烯烃,也可以催化α-烯烃齐聚,得到更高级的烯烃,丙烯二聚就是其中一种。由于丙烯二聚得到的各种六碳烯烃产物具有作为清洁剂、人造油和可塑剂的前体等方面的用途,而被广泛研究。 
过渡金属催化的丙烯二聚催化剂,常用的是镍金属络合物,如日本住友公司合成的环烷酸镍体系,2,3-二甲基丁烯的选择性为80%(Bull.Chem.Soc.Jpn.,1993,66,3069),但其活性不高;大连化物所的(β-酮亚胺)镍或钴络合物,二聚得到六碳烯烃的选择性为70-90%,二聚产物中甲基戊烯的含量为80%(发明专利申请公开说明书,2003,CN 1449867);而Eisen报道的二齿酰亚胺镍络合物/MMAO催化体系催化丙烯聚合表现出较高的催化活性,产物为各种己烯的混合物(Organometallics,2005,24,2645)。 
陶氏化学公司则用取代的二茂铀化合物催化丙烯二聚,得到4-甲基-1戊烯的选择性可以高达98%(美国公开专利,1989,US 4855523),但铀催化剂在使用过程中和使用后的处理上都存在安全方面的问题。此外,日本三井化学株式会社用非桥联型的二茂金属络合物用于催化丙烯二聚研究(世界公开专利,2006,WO 2006085531),所得产物成分复杂,主要产物为4-甲基-1-戊烯,其最高含量可达61.6%。 
目前对丙烯二聚的研究,选择性较好的主要还是一些非茂金属络合物,但所得产物都是各种齐聚的混合物。而茂金属络合物的二聚选择性也不是太好,也尚未见桥联型茂金属络合物用于丙烯二聚的报道。
