A series of phosphinimine ligands were designed and used in the Cu(i)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction of tetrazolo[1,5-a]pyridines and alkynes for the first time. By optimizing the reaction conditions, an efficient catalytic system (CuCl/2-PyCH2N[double bond, length as m-dash]P(t)Bu3) was developed to give 1-(pyridin-2-yl)-1,2,3-triazole derivatives in moderate to excellent yields (46-98%).
首次设计了一系列磷亚胺配体,并将其用于四氮唑并[1,5 - a]吡啶与炔烃的铜(I)催化叠氮 - 炔环加成(CuAAC)反应中。通过优化反应条件,开发了一种高效的催化体系(CuCl/2 - PyCH₂N = P(t)Bu₃),以中等至优异的产率(46 - 98%)得到1 - (吡啶 - 2 - 基) - 1,2,3 - 三唑衍生物。
