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 /Al 2 O 3 . 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.
