- Abstract
Amino-functionalized SBA-15 (SBA-Pr-NH) with a pore size of 6 nm has been used as an efficient and reusable heterogeneous solid-base catalyst for preparation of 2 H-indazolo[2,1- b]phthalazinetrione derivatives. The procedure involves three-component condensation of aromatic aldehydes, dimedone, and phthalhydrazide under solvent-free conditions. The catalyst can be easily removed from the reaction mixture and reused several times without substantial loss of reactivity.
