설명

애플리케이션

• Catalytic enhancement in organic synthesis: The study explores the use of Copper(II) chloride as a catalytic agent in the synthesis of 4-sulfonyl-1,2,3-triazoles, highlighting its role in sequential aerobic copper-catalyzed sulfonylation and Dimroth cyclization, providing a robust method for constructing triazole frameworks in medicinal chemistry and material science (Van Hoof et al., 2021).
