N-Methylation of a pyridoimidazolium salt and subsequent deprotonation afford a cationic NHC ligand. The spectroscopic characteristics of its Rh and Ir metal complexes reveal the reduced donor and enforced π-acceptor behaviour of this ligand system.
将吡啶并咪唑𬭩盐进行 N-甲基化,然后脱质子化,得到一个阳离子 NHC 配体。其 Rh 和 Ir 金属配合物的光谱特性揭示了该配体体系的供电子性降低和增强的π-接受能力。
