Cu3L2 metal–organic cages for A3-coupling reactions: reversible coordination interaction triggered homogeneous catalysis and heterogeneous recovery

Abstract

The reported Cu(II) metal–organic cage (Cu₃L₂, 1) can be a highly active reusable catalyst to homogeneously catalyze the A³-coupling reaction in CHCl₃ and can be heterogeneously recovered by simply adding 1,4-dioxane via formation of the insoluble metal–organic framework (Cu₃L₂(1,4-dioxane)_1.5, 2).
