The synthesis and characterization of two new complexes (IPr)Pd(acac)2 (1) and (IPr)Pd(acac)Cl (2) (IPr=(N,N'-bis(2,6-diisopropylphenyl)imidazol)-2-ylidene, acac=acetylacetonate) are described. Complex 2 can be prepared in a one-pot protocol in high yield. A study detailing the versatility of 2 to effectively catalyze a series of cross-coupling reactions is discussed.
两种新配合物(IPr)Pd(acac)2(1)和(IPr)Pd(acac)Cl(2)(IPr =(N,N'-双(2,6-二异丙基苯基)咪唑)的合成和表征描述了-2-亚烷基,acac =乙酰丙酮酸酯。配合物2可以一锅法高产率制备。讨论了详细研究2的多功能性以有效催化一系列交叉偶联反应的研究。
