Abstract: The condensation reaction of 2-substituted-4-formyl-1,2,3-triazole instead of the ordinary aldehydes with β-cyclohexanedione was investigated by acrylonitrile as a reaction medium, employing Mg(ClO4)2 as the catalyst. It was found that when it was carried out in the presence of Mg(ClO4)2, its selectivity gave the xanthenes. Further study showed that without additional catalyst this reaction could give xanthenediones ring-opening derivatives.

Key words: Xanthenes, Mg(ClO4)2, 2-substituted-4-formyl-1,2,3-triazole, Synthesis
