- Persistent Room-Temperature Radicals from Anionic Naphthalimides: Spin Pairing and Supramolecular Chemistry
-
N-Substituted naphthalimides (NNIs) have been shown to exhibit highly efficient and persistent room-temperature phosphorescence from an NNI-localized triplet excited state, when the N-substitution is a sufficiently strong donor and mediates an intramolecu

- Ionic liquids accelerate access to N-substituted-1,8-naphthalimides
-
The synthesis of N-substituted-1,8-naphthalimides is accelerated in the presence of the room temperature ionic liquid [BMIM][NO3]. Reaction times are reduced from 18 h in volatile organic compounds (VOCs) (PhCH 3, EtOH and THF) to 20 min in the ionic liquid [BMIM][NO 3]. The reaction yields are typically increased to >85% and the products are isolated by ethanol-mediated precipitation direct from the ionic liquid, requiring no further purification. Crown Copyright

- Matrix screening of substituted N-aryl-1,8-naphthalimides reveals new dual fluorescent dyes and unusually bright pyridine derivatives
-
A 3 × 14 matrix of substituted N-aryl-1,8-naphthalimides was synthesized for the evaluation and discovery of dual fluorescence. Because of their unique photophysical properties, these dual fluorescent systems represent an exception to the widely studied T

- A "green" route to perylene dyes: Direct coupling reactions of 1,8-naphthalimide and related compounds under mild conditions using a "new" base complex reagent, t-BuOK/DBN
-
The direct coupling reactions of 1,8-naphthalimide compounds efficiently occurred at 130 or 170 °C without the intervention of the leuco form dyes in the presence of base complex reagent, t-BuOK/1,5-diazabicyclo[4.3.0]non-5-ene (DBN), to give the corresponding perylene dyes in good yields with >95% purities. A possible mechanistic speculation for these oxidative coupling reactions is briefly discussed.

- Analgesic activity of cyclic imides: 1,8-Naphthalimide and 1,4,5,8- naphthalenediimide derivatives
-
In early studies, we have reported the synthesis and biological activities of several cyclic imides. The present study describes the analgesic activity of 1,8-naphthalimide and 1,4,5,8-naphthalenediimide derivatives in a standard murine model of analgesia. The pharmacological results show that all compounds studied, given intraperitoneally, produced significant inhibition of acetic acid-induced abdominal constrictions. At the ID50 (μmol/kg) level, these cyclic imide derivatives were about 40-270- fold more potent in this assay than aspirin and acetaminophen, two well-known and widely used analgesics. These results extend previous studies on the analgesic activity of cyclic imides. (C) 2000 Elsevier Science S.A.

- Efficient one-pot synthesis of N-substituted phthalimides/naphthalimides from azides and anhydrides by iodotrimethylsilane
-
N-Substituted phthalimides and naphthalimides have been obtained in good to excellent yields, employing chlorotrimethylsilane and sodium iodide (in situ generation of iodotrimethylsilane) from corresponding azides and anhydrides under mild conditions.

- N-SUBSTITUTED ISONAPHTHALIMIDES. FORMATION AND REACTION WITH AMINES
-
N-Substituted isonaphthalimides and N-substituted naphthalimides, as considered previously, are formed in the reaction of 1,8-naphthaloyl chloride with primary amines.The reaction of N-substituted isonaphthalimides with sterically unhindered amines leads to the N,N'-substituted diamides of 1,8-naphthalenedicarboxylic acid.In the case of sterically hindered amines it results in isomerization to the N-substituted naphthalimides.The thermolysis of the N,N'-substituted diamides of 1,8-naphthalenedicarboxylic acid leads to amines and N-substituted naphthalimides.
