SULFONIC ACID FUNCTIONALIZED NANOPOROUS SILICA (SBA-PR-SO3H) AS AN EFFICIENT CATALYST FOR THE ONE-POT SYNTHESIS OF 2H-INDAZOLO[1,2-B]PHTHALAZINE-TRIONES

SULFONIC ACID FUNCTIONALIZED NANOPOROUS SILICA (SBA-PR-SO3H) AS AN EFFICIENT CATALYST FOR THE ONE-POT SYNTHESIS OF 2H-INDAZOLO[1,2-B]PHTHALAZINE-TRIONES

Sulfonic acid functionalized SBA-15 (SBA-Pr-SO3H) with a pore size of 6 nm is an efficient catalyst in the green three-component condensation of phthalhydrazide, dimedone and aldehydes to give 2H-indazolo[1,2-b]plithalazine-triones under solvent-free conditions in excellent yields and short reaction times.
