【摘要】 本文成功制备了羰基铼中间体,借助于L16(43×26)正交实验细致研究了羰基铼配合物制备过程中多种因素的影响情况,确定了各羰基铼配合物的优化制备条件,同时进行了配合物稳定性的测试及部分理论计算。实验结果表明:pH值在5.8～7.2的接近中性区域内,配合物的产率相对较高;对于部分配体而言,pH值与配体之间的交互作用也存在一定影响;配体结构中含有不饱和杂环氮原子时,更易于与羰基铼核形成具有一定稳定性的配合物;对于简单配体,配合物总产率值随实验温度升高而升高;对于含有杂环的配体,在较低温度下,配合物的产率值即可达到90%以上,同时,即使在低浓度下,也可得到高产率的配合物。结果同时表明,羰基铼配合物具有足够的稳定性。更多还原

【Abstract】 Many factors containing temperature, time and so on which may influence the rate of complex remarkably during the preparation process are investigated by orthogonal test L16(43×26) in order to obtain the optimum condition towards the preparation of series of complexes of Re(I)-tricarbonyl intermediate and ligands, and several correlative property and theoretic calculation are measured. The results show that the optimum pH value is near to neutral district ranging from 5.8 to 7.2, and there are several interactions between pH value and ligands. When the heteroatom groups are contained in the ligands, the complexes are more stable, and also the complexes can be obtained even in very low concentration. The effect of temperature has relations with the structure of compounds. Re(I)-tricarbonyl complexes are stable adequately.更多还原
