conventional spectroscopic methods and elemental analyses. The incorporation of saturated N-heterocyclic carbenes into palladium precatalysts gives high catalyst activity in the Suzuki coupling of deactivated aryl chloride substrates in aqueous media. The complexes were generated in the presence of Pd(OAc)2 by in situ deprotonation of 2a–f. © 2005 Wiley Periodicals, Inc. Heteroatom Chem 16:557–561
从容易获得的起始材料中,制备了六种 1,3-二烷基-
咪唑啉溴化物 (2a-f),并通过常规光谱方法和元素分析对其进行了表征。将饱和的 N-杂环卡宾掺入
钯预催化剂中,在
水介质中失活的芳基
氯底物的 Suzuki 偶联中具有高催化剂活性。这些配合物是在 Pd(OAc)2 存在下通过 2a-f 的原位去质子化产生的。© 2005 Wiley Periodicals, Inc. 杂原子
