Truly heterogeneous with retention of its high performance: The 1,3-dipolar cycloaddition of azomethine imines to terminal alkynes was efficiently promoted by the easily prepared, inexpensive, supported copper hydroxide, Cu(OH) x/Al2O3. Various kinds of azomethine imines and terminal alkynes could be utilized as dipoles and dipolarophiles, respectively, to form the corresponding N,N-bicyclic pyrazolidinone derivatives in high yields.

A simple dinuclear copper complex [Cu(μ-OH)(tmen)]2Cl 2 (tmen = N,N,N′,N′,-tetramethylethylenediamine) could act as an effective precatalyst for the 1,3-dipolar cycloaddition of pyrazolidinone-based dipoles to terminal alkynes to pro
