The N9-imidazolium-substituted adenine derivative H-1Cl reacts with [MCl2(Cp*)]2 (M = Rh, Ir) in acetonitrile at 75 °C with formation of the CNHC^N3adenine chelate complexes [3]Cl and [4]Cl, respectively. At higher temperature (125 °C), double deprotonation of H-1Cl by NaOAc was observed and the reaction with [MCl2(Cp*)]2 (M = Rh, Ir) yields the chelate complexes [5] and [6] bearing a unique CNHC^Cazolato chelate ligand. The N7-protonation of the ring-nitrogen atoms of the azolato donor in [5] and [6] was also performed to give the complexes bearing a CNHC^CpNHC chelate ligand.

由N9-咪唑鎓取代的腺嘌呤获得的具有螯合Di-NHC配体的Rh III和Ir III配合物的合成
N9-咪唑鎓取代的腺嘌呤衍生物H- 1 Cl与[MCl 2（Cp *）] 2（M = Rh，Ir）在乙腈中于75°C反应，形成C NHC ^ N3腺嘌呤螯合物[ 3 ]。 Cl和[ 4 ] Cl。在较高温度（125°C）下，观察到NaOAc对H- 1 Cl进行了双重去质子反应，与[MCl 2（Cp *）] 2（M = Rh，Ir）的反应生成了螯合物[ 5 ]和[ 6 ] ]带有独特的C NHC ^ C azolato螯合配体。还进行了[ 5 ]和[ 6 ]中的氮杂给体的环氮原子的N7质子化反应，得到了带有C NHC ^ C pNHC螯合物的配合物。
