was successfully synthesized from LaCl3 and 1,1′ : 4′,1′ ′: 4′′,1′′′ : 4′′′,1′′′′-quinquephenyl]-2,2′′,2′′′′,5′′-tetracarboxylic acid (H4qptca) by conventional solvothermal method. Initial studies showed that it was an efficient heterogeneous catalyst for the Friedel-Crafts alkylation of indole and pyrrole with β-nitrostyrene with a wide substrate scope.
一种新型基于 La(III) 的二维 (2D)
金属有机骨架 [La 2/3 (qptca) 1/2 ] 成功地由 LaCl 3和 1,1' : 4',1' 合成: 4'',1''' : 4''',1''''-quinquephenyl]-2,2'',2'''',5''-四
羧酸 (H 4 qptca) 常规溶剂热法. 初步研究表明,它是一种高效的多相催化剂,适用于
吲哚和
吡咯与
β-硝基苯乙烯的 Friedel-Crafts 烷基化反应,具有广泛的底物范围。
