【摘要】：吡唑硼配體是一種陰性的配體，它含有氮原子，具有很好的配位能力，可以跟一些主族元素或者過(guò)渡金屬反應(yīng)形成一些具有新穎結(jié)構(gòu)的配合物。吡唑硼配體具有化學(xué)結(jié)構(gòu)新穎,變化多樣,功能齊全等特征,它已成為當(dāng)前金屬有機(jī)化學(xué)領(lǐng)域中的前沿課題和研究的熱點(diǎn)。 與吡唑類配體相比，吡唑膦類配體的配位性更強(qiáng)。吡唑膦類配體中同時(shí)含有N和P兩種配位能力不同的原子，且它們都采取sp2雜化成鍵方式，都有一對(duì)孤對(duì)電子，使其配位能力更強(qiáng)，能與周期表中的大部分金屬以不同的配位方式結(jié)合，形成結(jié)構(gòu)多樣的配合物。 基于以上特性，我們決定合成雙吡唑膦硼鉀配體，雙吡唑膦甲烷配體，并合成一系列配合物。本文將進(jìn)行以下研究與探討： 1.合成雙(1,2,4-二唑膦)硼鉀配體 1,2,4-二唑膦與硼氫化鉀作為原料，用甲苯作為溶劑，，按摩爾比為2:1進(jìn)行反應(yīng)，合成一種新的陰性雙齒配體，即雙(1,2,4-二唑膦)硼鉀配體。研究其合成方法,將所得產(chǎn)物用熔點(diǎn)，核磁，紅外，X射線單晶衍射等分析方法進(jìn)行表征，得到其單晶結(jié)構(gòu); 2.雙(1,2,4-二唑膦)硼鉀鹽與鎳配合物的合成研究 將新合成的雙(1,2,4-二唑膦)硼鉀配體與溴化鎳按摩爾比為2:1進(jìn)行反應(yīng)，最后得到的配合物用紅外，熔點(diǎn)，順磁共振，X射線單晶衍射等分析方法進(jìn)行表征，最后得出該配合物具有順磁性; 3.雙(1,2,4-二唑膦)甲烷與鎳配合物的合成研究 1,2,4-二唑膦與二氯甲烷作為原料合成雙(1,2,4-二唑膦)甲烷，并將其與溴化鎳按摩爾比為2:1進(jìn)行反應(yīng)，將所得產(chǎn)物用紅外，熔點(diǎn)，核磁，X射線單晶衍射等分析方法進(jìn)行表征，我們得出該配合物具有反鐵磁性。
[Abstract]:Pyrazole boron ligands are negative ligands. They contain nitrogen atoms and have good coordination ability. They can react with some host elements or transition metals to form some novel complexes. Pyrazolium boron ligands are characterized by novel chemical structure, diverse changes and complete functions. It has become a hot topic in the field of organometallic chemistry. Compared with pyrazole ligands, pyrazole phosphine ligands have stronger coordination properties. Pyrazophosphonium ligands contain atoms with different coordination capacities of N and P, and both of them are bonded by sp2 heterogeneity, and each has a pair of solitary pairs of electrons, which make their coordination ability stronger. It can bind with most metals in the periodic table in different coordination ways to form complex with various structures. Based on the above characteristics, we have decided to synthesize bispyrazophosphonium boron potassium ligands and bispyrazophosphone-methane ligands, and to synthesize a series of complexes. This article will carry on the following research and discussion: 1. A new negative didentate ligand, Bis (1H 2H 2N 4 diazophosphonium) boron potassium ligand, was synthesized by reaction with potassium borohydride with toluene as solvent and massage at 2:1, and a new negative ligand, Bis (1H 2H 2N 4 diazophosphonium) boron potassium ligands, was synthesized. The synthesis method was studied. The products were characterized by melting point, nuclear magnetic field, infrared X-ray single crystal diffraction and so on, and the single crystal structure was obtained. 2. Study on the Synthesis of Bis (1H _ 2N _ 4-Diazophosphonium) Boropotassium Salts and Nickel complexes; reaction of the newly synthesized Bis (1H _ 2N _ 4-Diazophosphonium) Boron potassium Ligand with Nickel bromide at 2:1 molar ratio, the resulting complexes were synthesized by IR, melting point, Paramagnetic resonance X-ray single crystal diffraction and other analysis methods were used to characterize the complex. Finally, it was found that the complex had paramagnetic properties. Study on the Synthesis of Bis (1H 2H 2N 4 Diazophosphonium) methane and Nickel complex; the synthesis of bis (1h2h2zophosphonium diazophosphine) methane with dichloromethane as raw material and the reaction with nickel bromide at 2:1 in molar ratio, the products were obtained by IR, melting point, The complex was characterized by NMR X-ray single crystal diffraction and we found that the complex has anti-ferromagnetism.
