Description
技术领域
本发明涉及一种合成金属氮杂环卡宾配合物的方法。
背景技术
1968年和Wanzlick各自独立发表了第一例氮杂环卡宾(NHCs)配合物,两人使用碱性金属化合物脱去咪唑盐质子得到咪唑-2-碳烯配合物(K.1,3-Dimethyl-4-imidazolinyliden-(2)-pentacarbonylchrom einneuer übergangsmetall-carben-komplex.J.Organomet.Chem.1968,12,42-43;Wanzlick,H.W.;Schonherr,H.J.Direct Synthesis of a MercurySalt-Carbene Complex.Angew.Chem.1968,80,154;Angew.Chem.Iht.Ed.Engl.1968,7,141-142)。1991年Arduengo等人结晶得到了第一例游离的氮杂环卡宾(Arduengo III,A.J.;Harlow,R.L.;Kline,M.A stable crystallinecarbene.J.Am.Chem.Soc.1991,113,361-363),这激起了人们对游离卡宾及其金属配合物化学的广泛兴趣。1995年Herrmann等人首次将氮杂环卡宾金属配合物用于催化有机反应,由于该类化合物作为催化剂有着很多优越的性质(Herrmann,W.A.;Elison,M.;Fischer,J.;Kocher,C.;Artus,G.R.J.Metal Complexes of N-Heterocyclic Carbenes-A New Structural Principlefor Catalysts in Homogeneous Catalysis.Angew.Chem.Iht.Ed.Engl.1995,34,2371-2374),十几年来氮杂环卡宾过渡金属化合物作为催化剂在有机反应中的应用得到了快速的发展。
到目前为止,氮杂环卡宾配合物在催化各种各样的有机反应中已经取得了巨大的成功(Diez-Gonzalez,S.;Marion,N.;Nolan,S.P.N-HeterocyclicCarbenes in Late Transition Metal Catalysis.Chem.Rev.2009,109,3612.)。氮杂环卡宾过渡金属催化剂在药物合成、高分子材料合成中发挥着越来越重要的作用。
催化剂是否易于制备往往很大程度上决定了其大规模应用尤其是工业应用的可能性。制备金属氮杂环卡宾配合物有多种方法,最为常用的包括:(1)利用游离卡宾和金属盐类配位反应;(2)咪唑盐和碱性金属盐脱质子原位反应;(3)金属前驱体和银氮杂环卡宾配合物金属交换反应。第一种方法需要无水无氧的苛刻条件和特殊的碱试剂,而且很多游离卡宾不稳定,容易自身聚合。第二种方法要求先制备无水金属醋酸盐、金属醇盐或金属氨基化合物,但是这些化合物本身就很难制备与储存。第三种方法较为直接简单,不足的是需要使用昂贵的氧化银试剂制备银氮杂环卡宾配合物,而银氮杂环卡宾配合物往往对光比较敏感,有时还会诱导氧化降解卡宾配体。
发明内容
本发明提供一种简单易行的制备金属氮杂环卡宾配合物的方法。
一种合成金属氮杂环卡宾配合物的方法,包括:
在有机溶剂中加入镍氮杂环卡宾配合物和金属前驱体,反应完毕结晶纯化得到金属氮杂环卡宾配合物;
所述的金属前驱体的通式表示为M(L)nClm;
其中,M为钯(II)、铂(II)、钴(II)、钴(I)、铑(I)、铱(I)、铁(II)、钌(II)、金(I)或镍(II);
L为三苯基膦、1,5-环辛二烯、二甲硫醚、乙腈、苄腈、苯甲腈、二甲基亚砜、烯丙基或对伞花烃;
n=0、1、2或3;
m=1或2。
用镍氮杂环卡宾配合物替代传统的银氮杂环卡宾配合物作卡宾转移试剂,成本低廉,产率较高。该方法对氮杂环卡宾配体官能团容忍性好,对金属前驱体适用性广。
所述的镍氮杂环卡宾配合物的结构式为:
其中,R1为烷基、芳基、2-嘧啶基、2-吡啶基、2-吡啶甲基、4-连三唑甲基、1-吡唑甲基、2-邻菲罗啉基、2-喹啉基、2-喹啉甲基、二苯膦基甲基、二苯膦基乙基或其各自的衍生物;
R2为氮杂环或膦官能团,包括2-嘧啶基、2-吡啶基、2-吡啶甲基、4-连三唑甲基、1-吡唑甲基、2-邻菲罗啉基、2-喹啉基、2-喹啉甲基、二苯膦基甲基、二苯膦基乙基或其各自的衍生物;
X-为PF6 -、Cl-、Br-、I-或BF4 -。
氮杂环官能团化具有性质稳定、结构多变、催化反应时稳定催化中心的特点,优选的R2为氮杂环官能团,包括2-嘧啶基、2-吡啶基、2-吡啶甲基、4-连三唑甲基、2-邻菲罗啉基或其各自的衍生物。
镍氮杂环卡宾配合物和金属前躯体在乙腈中的溶解性很好,而反应生成的NiCl2在乙腈中几乎不溶,用乙腈作溶剂有利于镍氮杂环卡宾配合物和金属前躯体反应的进行。
镍氮杂环卡宾配合物和金属前驱体的反应属于复分解反应,根据产物中氮杂环卡宾配体个数的不同,要求镍氮杂环卡宾配合物的中心离子Ni2+与金属前驱体M(L)nClm中的金属离子的摩尔比为1∶1~2,又金属前驱体中一般包含1~2个金属离子,这就要求所述的镍氮杂环卡宾配合物和金属前驱体的摩尔比为1∶0.5~2。
所述的反应温度为35~70℃,反应时间为1~24小时。根据镍氮杂环卡宾配合物和金属前驱体种类的不同,可以选择不同的反应温度或反应时间,以便反应更完全,获得更高的产物收率。
所述的金属前驱体为钯前驱体、铂前驱体、钴前驱体、铑前驱体、铱前驱体、铁前驱体、钌前驱体、金前驱体或镍前驱体。
带有有机配体的金属前驱体在有机溶剂中的溶解性往往较一般的金属前驱体要好,这有利于金属前驱体和镍氮杂环卡宾配合物反应的进行。
优选的钯前驱体为(1,5-环辛二烯)二氯化钯(II)、双(三苯基膦)二氯化钯(II)、双(乙腈)二氯化钯(II)、双(苄腈)二氯化钯(II)或氯化烯丙基钯(II)二聚物。

优选的钴前驱体为氯化钴(II)、双(三苯基膦)二氯化钴(II)或三(三苯基膦)氯化钴(I)。氯化钴(II)易溶于有机溶剂。
优选的铑前驱体为双(环辛烯)氯化铑(I)二聚体、三(三苯基膦)氯化铑(I)、羰基双(三苯膦基)氯化铑(I)、降冰片二烯氯化铑(I)二聚体或聚合二羰基氯化铑(I)。
优选的铱前驱体为(1,5-环辛二烯)氯化铱(I)二聚体或羰基氯双(三苯基磷基)铱(I)。
优选的铁前驱体为氯化亚铁(II)或双(三苯基膦)二氯化铁(II)。氯化亚铁(II)廉价易得,溶于有机溶剂。
优选的钌前驱体为对伞花烃二氯化钌(II)二聚体、三(三苯基膦)二氯化钌(II)、(1,5-环辛二烯)二氯化钌(II)、三(三苯基膦)羰基氢氯化钌(II)或羰基氯化钌(II)聚合物。
优选的金前驱体为(三苯基膦)氯化金(I)或二甲硫醚氯化金(I)。
优选的镍前驱体为双(三苯基膦)氯化镍(II)或乙二醇二甲醚氯化镍(II)。
镍氮杂环卡宾配合物和金属前驱体反应的代表性的化学反应方程式可以表示为:
镍氮杂环卡宾配合物与金属前驱体的反应属于复分解反应,在有机溶剂中,镍氮杂环卡宾配合物与金属前驱体相互交换金属离子,结合生成NiCl2沉淀,使镍氮杂环卡宾配合物与金属前驱体的反应方向朝着生成金属氮杂环卡宾配合物的方向进行,反应完毕结晶纯化得到金属氮杂环卡宾配合物。
本发明通过上述方法合成了一系列钯、铂、钴、铑、铱、铁、钌、金、镍氮杂环卡宾配合物,并对各金属氮杂环卡宾配合物进行了表征。镍氮杂环卡宾配合物作为卡宾转移试剂,成本低廉。本方法对卡宾配体官能团容忍性好,对金属前驱体适用性广,反应条件温和,后处理简单,产率较高,且无需使用特殊的贵重试剂,是对过渡金属氮杂环卡宾配合物合成方法的进一步发展。本发明为低成本合成过渡金属氮杂环卡宾配合物催化剂提供了简单易行的方法,为过渡金属氮杂环卡宾配合物催化剂的工业化应用奠定了基础。
