Porous Calcium Hydroxyapatite as an Efficient Catalyst for Synthesis of Pyrazolines via 1,3‐Dipolar Cycoloaddition Under Solvent‐Free Microwave Irradiation
Adsorbed on porous calcium hydroxyapatite, 1,3-dipolar cycloaddition of diphenylnitrilimine on olefins is readily catalyzed under solvent-free microwaves irradiation. The pyrazolines are obtained in few minutes with high yields. Specific surface of porous calcium hydroxyapatite and microwaves effects are discussed.
