我们首次证明了四核ZnII 2LnIII 2配位簇（CCs）作为吲哚与一系列反式-β-硝基苯乙烯的Friedel-Crafts（FC）烷基化反应的高效催化剂。反应在室温下以良好至优异的产率（76%-99%）进行，催化剂负载量低至1.0摩尔%。
We demonstrate for the first time the high efficacy of tetranuclear ZnII2LnIII2 coordination clusters (CCs) as catalysts for the Friedel–Crafts (FC) alkylation of indoles with a range of trans-β-nitrostyrenes. The reaction proceeds in good to excellent yields (76%–99%) at room temperature with catalyst loadings as low as 1.0 mol %.
