Azide-tagged Cu(I)-NHC reacts in an 'auto-click' process to furnish complexes functionalized by 1,2,3-triazoles bearing diverse substituents. The resulting Cu(I) complexes are amenable to further transmetallation to Au(I). The whole strategy proceeds with mild conditions and constitutes an efficient entry to functionalised metal-NHCs with biorelevant moieties.
叠氮标记的Cu(I)-N-杂环卡宾在“自动点击”过程中发生反应,生成由带有不同取代基的1,2,3-三唑官能化的配合物。所得的Cu(I)配合物易于进一步转金属化为Au(I)。整个策略在温和的条件下进行,是一种高效合成带有生物相关基团的官能化金属-N-杂环卡宾的方法。
