摘要
本文通过逐级取代反应,合成了三种新的含有1,1-二(二苯基膦)二茂铁(dppf)配体的π-键合混合配体零价钯双核配合物,并用红外光谱,元素分析,电子光谱,~1H-NMR及^(31)P-NMR对其进行了表征.利用循环伏安法测得三个配合物的茂基Fe(Ⅱ)的氧化还原电位.提出了它们的可能结构.
Three new π-bonding mixed-ligand Pd(O)binuclear complexes with dppf ligands were prepared through step-by-step substitution reactions.These complexes were characterized through elemental analysis,IR,electronic and H-NMR,^(31)P-NMR spectra.Their redox wave peak potentials of the ferrocenyl group were measured by using CV method.The probable structures of these new complexes were proposed.
