Abstract

Metal-organic frameworks with regular pore structures provide powerful platforms for the design of single-site metal catalysts for chemical transformation. In this paper, we develop a facile, stable and recyclable MOF-supported Cu(II) catalyst, MIL-101-SO₃Cu. It shows extremely high activity for the A³ coupling of alkynes, aldehydes and amines. The turnover frequency can reach 6.8 × 10⁵ h⁻¹ under neat conditions, which is the highest so far reported for the reaction. The high activity is because the specific structure of the MIL-101-SO₃ support enables a single-site dispersion and an unhindered open environment for the metal ion. MIL-101-SO₃Cu also exhibits high activity for the one-pot cascade reactions combining A³ coupling and 5-endo-dig cyclization.
