In an article, author is Zare, Abdolkarim, once mentioned the application of 3648-20-2, Safety of Diundecyl phthalate, Name is Diundecyl phthalate, molecular formula is C30H50O4, molecular weight is 474.7156, MDL number is MFCD00043729, category is phthalazine. Now introduce a scientific discovery about this category.
Novel ionic liquid N,N-diethyl-N-sulfoethanaminium hydrogen sulfate: Design, characterization, and application as a highly efficient catalyst for the production of triazolo[1,2-a]indazole-triones and 2H-indazolo[2,1-b]phthalazine-triones
A novel BrOnsted acidic ionic liquid namely N,N-diethyl-N-sulfoethanamminium hydrogen sulfate ([Et3N-SO3H]HSO4) was synthesized, and characterized using FT-IR, H-1 NMR, C-13 NMR, and mass data. Then, its catalytic activity was examined for the preparation of triazolo[1,2-a]-indazole-triones and 2H-indazolo[2,1-b]phthalazine-triones by the one-pot multi-component condensation of arylaldehydes with dimedone and 4-phenylurazole/2,3-dihydrophthalazine-1,4-dione under solvent-free conditions. [Et3N-SO3H]HSO4 efficiently promoted the reaction to afford the products in high yields and in short reaction times.
