摘要
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.
