aluminium iii chloride catalyzed three component condensation of aromatic aldehydes nitroalkanes and Sodium Azide for the synthesis of 4 aryl nh 1 2 3 triazoles
Advanced Synthesis & Catalysis, 2016Co-Authors: Qinquan Hu, Xiaocong Deng, Yanjun Li, Yunfeng ChenAbstract:An aluminium(III) chloride-catalyzed three-component reaction of aromatic aldehydes, nitroalkanes, and Sodium Azide has been developed; this reaction sequence can be applied to a broad substrate scope and affords the corresponding 4-aryl-NH-1,2,3-triazoles in good to excellent yields. The milder reaction conditions and easier operation make this AlCl3-catalyzed protocol more advantageous for the synthesis of 4-aryl-NH-1,2,3-triazoles.
