antranilic acid is an intermediate material which we can produce by hofmann's rearrangement reaction. in this process phithalimide is a main reactant. one procedure for produceing phthalimide is the reaction of phithalic anhydride with urea in the presence of acetic acid. in this research, the kinetics of this reaction was studied at 115 c. we found that the reaction of phthalic anhydride ...

A SO3 H-containing solid acid namely SO3 H-functionalized phthalimide (SFP) was synthesized from phthalimide and chlorosulfonic acid, and identified by studying its FT-IR, 1 H and 13C NMR, Mass, XRD, TG and DTG spectra. Afterward, its catalytic activity was examined for the solvent-free condensation of dimedone (5,5-dimethyl-1,3-cyclohexanedione) (2 eq.) with arylaldehydes (1 eq.). The results ...

Two highly efficient protocols for the production of bis-coumarins under solvent-free conditions have been introduced. The reaction of 4-hydroxycoumarin (2 eq.) with arylaldehydes (1 eq.) using phthalimide-N-sulfonic acid (PhtSA) or isatin-N-sulfonic acid (IsSA), as solid-acid catalysts, afforded the mentioned compounds with good to excellent yields in short times.Briefly, we have introduced tw...

THE TITLE COMPOUND [SYSTEMATIC NAME: 2-(1H-1,2,3-benzotriazol-1-ylmeth-yl)isoindole-1,3-dione], C(15)H(10)N(4)O(2), was prepared by the reaction of 1H-benzotriazole and 2-bromo-methyl-isoindole-1,3-dione. The benzotriazole and isoindole units are almost planar and make a dihedral angle of 70.2 (1)° (mean planes include C and N atoms). A weak C-H⋯O intra-molecular hydrogen bond involving a carbo...
