Description

一种芳基-芳基联苯类化合物的制备方法
技术领域
本发明涉及一种芳基-芳基联苯类化合物的制备方法。
背景技术
芳基-芳基联苯类化合物是最常见的结构单元之一,常见于一些药物及其中间体和功能材料的结构中。因此对于芳基-芳基联苯类化合物的构建一直是金属有机化学研究的重点内容。
Suzuki偶联反应是制备芳基-芳基联苯类化合物最常用的一种方法。其特点是采用有机硼试剂。在所报道的各种有关Suzuki偶联反应的研究中,有机硼酸是使用最广泛的一种硼试剂。然而,研究发现,有机硼酸具有明显的缺点:1)常以二聚或三聚硼酸酯的形式存在,导致有机硼酸难以纯化和难以定量;2)易于发生自身偶联反应,因此反应中常需要过量的有机硼酸的参与;3)对一些常规的合成条件敏感,不适合存在于底物结构的修饰中。因此,研究新的有机硼试剂在Suzuki偶联反应中的应用具有了重要意义。研究发现,芳基三氟硼酸钾作为硼试剂可克服有机硼酸以上缺点,正逐渐成为有机硼酸的理想替代物。然而,对于利用卤代芳烃与芳基三氟硼酸钾的Suzuki反应来制备芳基-芳基联苯类化合物的方法却较少,尤其是以水作为介质的绿色合成方法。
2002年,Molander小组首次研究了水中卤代芳烃与芳基三氟硼酸钾的反应。研究发现,只有当卤代芳烃的结构中含有-OH或-COOH,反应才可以进行(Molander,G.A.;Biolatto,B.J.Org.Chem.,2003,68,4302-4314.Molander,G.A.;Biolatto,B.Org.Lett.,2002,4,1867-1870.)。这种对卤代芳烃底物的特殊要求大大的限制了芳基-芳基联苯类化合物的绿色合成。
发明内容
本发明的目的是提供一种芳基-芳基联苯类化合物的制备方法。
它是将0.5mmol的溴代芳烃,0.6mmol的芳基三氟硼酸钾,1mmol的碱,1-2mol%的醋酸钯于反应器中,加入3mL水和3g聚乙二醇,在80℃下搅拌1-4h小时,用乙醚萃取,旋干溶剂后,分离即得产品。
本发明的优点:
1)选择水和聚乙二醇作为反应介质,无有机溶剂参与,对环境无污染,为绿色反应体系;
2)该方法不需要任何配体或惰性气体的保护,在空气中能很好的进行;
3)该反应在温和的条件下进行,反应时间短,反应产率高,经过简单的乙醚萃取就能达到产物和反应体系的分离;
4)该方法可以允许底物中多种官能团的存在。
具体实施方式
本发明采用水和聚乙二醇作为反应溶剂,在碱作用和醋酸钯的存在下,无需配体参与和惰性气体的保护,溴代芳烃和芳基三氟硼酸钾发生交叉偶联反应,得到各种不同的芳基-芳基联苯类化合物。反应的方程式为:
其中,R为4-CH3、4-NO2、4-OMe、4-F、4-COCH3、4-CN、2-CH3、3-CH3、4-OH或4-NH2,R’为4-CH3、4-OMe、2-CH3、3-CH3或4-CF3。聚乙二醇为聚乙二醇400、聚乙二醇600、聚乙二醇1000、聚乙二醇2000、聚乙二醇4000或聚乙二醇6000。碱为碳酸钾、碳酸钠、磷酸钾、氢氧化钾或氢氧化钠。反应温度为80℃,反应时间为1-4小时。醋酸钯的用量为1-2mol%。
