A bi-functional sugar-based surfactant ALA14 was designed as the ligand and micelle constructor and demonstrated to promote the copper-catalyzed C–X coupling reaction in water. The nature of this micelle, formed by sugar-based surfactants, was investigated with CMC, DLS, and TEM, by which encapsulation and aggregation of the substrates in micelles were verified. Additionally, it was addressed by 1H-NMR
