摘要
以二氯化钯为原料,在碱性条件下有效地制备了乙酰丙酮钯(II),用无水乙醇提纯后产率达到92.2%。通过元素分析、电子光谱、IR、MS、1HNMR,进一步确证了所制得样品的结构与性质。结果表明:乙酰丙酮钯属于低自旋的平面正方型配合物,在反应动力学上是稳定的;配合物中螯合环和离域e键的形成使Pd-O键加强,配合物更稳定。
Palladium(II)acetylacetonate was prepared by reacting PdCl2 with acetylacetone in basic solution, and the product was purified by recrystallization in ethanol, reaching a yield of 92.2%. The chemical structure of palladium(II)acetylacetonate was determined by using elemental analysis, electronic spectra, infrared spectra, mass spectra and H nuclear magnetic resonance. The results 1 showed that Pd(acac)2 is a square plannar coordination compound with acetylacetone acting as a bichelating ligand. In the chelating ring, conjugate e bonds are formed, which further strengthen the Pd-O coordination bonds and make Pd(acac)2 a stable compound.
