Description
本发明得到国家自然科学基金面上项目(21471113)，天津市教委项目资助(20140506)，天津师范大学中青年教师学术创新推进计划项目和天津市高等学校创新团队培养计划资助(TD12-5038)。
技术领域
本发明属于无机合成技术领域，涉及铜配合物{[Cu(tatrz)2(H2O)2](BF4)2}
(1) (tatrz = 1-[9-(1H-1,2,4-三氮唑-1-基)蒽-10-基]-1H-1,2,4-三氮唑)的制备方法及作为4-吡啶苯硼酸偶联反应的催化剂方面的应用。
背景技术
以过渡金属络合物催化进行高选择性合成的研究一直是一个活跃的领域。用普通合成手段难于实现的反应，有事使用过渡金属络合物能够在温和条件下一步完成。因此，采用金属络合物做催化剂来开发高选择性、高转化率的有机合成反应，是十分令人感兴趣的课题。有机合成中一般常用的过渡金属有镍、钯、铜、钌、铑、锰等，而其中钯络合物显示出多样性催化功能。钯催化偶联反应种类很多，这些反应在合成天然产物、聚合物、功能材料、液晶、药物分子及生物活性化合物中均有广泛的用途。但钯催化剂相对昂贵，如果能用廉价的铜配合物取代昂贵的钯催化剂，实现反应的进程，不仅可以节约成本，而且有望工业化生产。
1,2,4-三唑及其衍生物兼有吡唑和咪唑的配位特点，是配位能力较强的桥连配体，目前已合成并表征了大量的单核、多核和多维化合物。这些配体能够以1,2位上的氮原子与金属离子配位形成N1,N2-桥连模式，对于4位未取代的1,2,4-三唑衍生物能通过2,4位上的氮原子形成N2,N4-桥连模式，这种N2,N4-桥连模式同金属酶中咪唑的N1,N3-桥连模式类似。对于三唑类化合物的特殊用途还表现在分子器件化的设计上，合成具有不同维数的金属配合物乃是完成器件化至关重要的一步。
本发明即是选用Cu(BF4)2和1-[9-(1H-1,2,4-三氮唑-1-基)蒽-10-基]-1H-1,2,4-三氮唑(tatrz)在常温条件下来制备铜配合物{[Cu(tatrz)2(H2O)2](BF4)2}
(1)。催化实验证明，该配合物可作为4-吡啶苯硼酸偶联反应的催化剂得以应用。

晶体结构测定采用APEX II CCD单晶衍射仪，使用经过石墨单色化的Mokα射线(λ = 0.71073 Å)为入射辐射，以ω-2θ扫描方式收集衍射点，经过最小二乘法修正得到晶胞参数，从差值傅立叶电子密度图利用软件解出晶体结构，并经洛仑兹和极化效应修正。所有的H原子由差值傅立叶合成并经理想位置计算确定。详细的晶体测定数据见表1。结构基元见图1，配合物的三维结构见图2。

Cu(BF4)2和1-[9-(1H-1,2,4-三氮唑-1-基)蒽-10-基]-1H-1,2,4-三氮唑(tatrz)的摩尔比为1:1；
我们还尝试过其他比例，比如Cu(BF4)2和1-[9-(1H-1,2,4-三氮唑-1-基)蒽-10-基]-1H-1,2,4-三氮唑(tatrz)的摩尔比为2:1，则无论水热反应时间的长短，都得不到晶态化合物。因此Cu(BF4)2和1-[9-(1H-1,2,4-三氮唑-1-基)蒽-10-基]-1H-1,2,4-三氮唑(tatrz)的摩尔比为1:1是最佳反应配比。

以过渡金属络合物催化进行高选择性合成的研究一直是一个活跃的领域。用普通合成手段难于实现的反应，有事使用过渡金属络合物能够在温和条件下一步完成。因此，采用金属络合物做催化剂来开发高选择性、高转化率的有机合成反应，是十分令人感兴趣的课题。有机合成中一般常用的过渡金属有镍、钯、铜、钌、铑、锰等，而其中钯络合物显示出多样性催化功能。钯催化偶联反应种类很多，这些反应在合成天然产物、聚合物、功能材料、液晶、药物分子及生物活性化合物中均有广泛的用途。但钯催化剂相对昂贵，如果能用廉价的铜配合物取代昂贵的钯催化剂，实现反应的进程，不仅可以节约成本，而且有望工业化生产。
1,2,4-三唑及其衍生物兼有吡唑和咪唑的配位特点，是配位能力较强的桥连配体，目前已合成并表征了大量的单核、多核和多维化合物。这些配体能够以1,2位上的氮原子与金属离子配位形成N1,N2-桥连模式，对于4位未取代的1,2,4-三唑衍生物能通过2,4位上的氮原子形成N2,N4-桥连模式，这种N2,N4-桥连模式同金属酶中咪唑的N1,N3-桥连模式类似。对于三唑类化合物的特殊用途还表现在分子器件化的设计上，合成具有不同维数的金属配合物乃是完成器件化至关重要的一步。
本发明即是选用Cu(BF4)2和1-[9-(1H-1,2,4-三氮唑-1-基)蒽-10-基]-1H-1,2,4-三氮唑(tatrz)在常温挥发条件下来制备铜配合物{[Cu(tatrz)2(H2O)2](BF4)2}
(1)。催化实验证明，该配合物可作为4-吡啶苯硼酸偶联反应的催化剂得以应用；
在25 mL烧杯中称取1.1 g 4-吡啶苯硼酸，0.2 g Cs2CO3，3 mL DMF和0.1 g催化剂(配合物1)，室温下搅拌1小时，TLC监测(PE:EA = 1:1)反应完全，10 mL
CH2Cl2萃取产品后再用20 mL蒸馏水洗涤，有机相用污水MgSO4干燥，过滤，脱溶，得到的粗产品以石油醚洗脱过柱，得到4,4'-联吡啶。
