| 中文摘要: |
| 通过多步膦烷基化反应和还原脱苄基反应，成功合成了一种具有双碳链连接体的新型四齿膦配体，该配体中含有一个1,4-二磷环己烷的结构以及两个—P(H)2．研究了配体合成过程中含磷环的顺反异构现象，以及该配体与Ni2+的配位反应． 结果表明，该膦配体能够很好地与Ni2+螯合，形成平面四边形配位的配合物Ni{［PH2(CH2)3］2P2C4H8}2+，使用核磁共振和计算化学等方法对其进行了表征和结构预测． |
| 英文摘要: |
| A new type of tetradentate phosphine ligand containing two carbon chain linkers is synthesized through multi step phosphine alkylation reaction and reductive debenzylation reaction. This ligand has a 1,4 diphosphocyclohexane skeleton and two —P(H)2. The cis trans isomerization of the phosphorus containing ring in its preparation is discussed. The coordination reaction between the ligand and Ni2+ is studied. The results show that this tetradentate phosphine ligand can chelate with Ni2+ to form a planar quadrilateral coordination complex Ni{［PH2(CH2)3］2P2C4H8}2+. Nuclear magnetic resonance and computational chemistry methods are used to characterize and predict its structure. |
