In this paper, the homogeneous catalytic system of CuSO4·5H2O/NaAsc was used to realize the Sonogashira reaction of aryl iodides and terminal alkynes. This catalytic system replaces the general catalytic system of Pd/Cu-bound phosphorus ligand, which has the advantages of cheap catalyst, simple post-treatment, reaction under homogeneous conditions, and meets the requirements of green chemistry.

Key words: aryl iodides, terminal alkynes, CuSO4·, 5H2O/NaAsc, Sonogashira coupling
