Benzimidazoles of Formula I below are inhibitors of protein tyrosine kinases, and are useful in treating cellular proliferation. ##STR1## The compounds are especially useful in treating cancer, atherosclerosis, restenosis, and psoriasis.
quantum yields (up to 88.3%) and short decay times (4.8–55.2 μs). The emission maxima can be fine-tuned from 529 nm to 577 nm, depending upon the number and position of methoxy substituent on the NˆP ligand. Especially, complex 5 exhibits phosphorescence (533 nm) with photoluminescence quantum yield of 70.5% and decay time of 19.5 μs, implying its potential to serve as a phosphor for organic light emitting
Fe(acac)<sub>2</sub>/TBHP-promoted synthesis of 11-functionalized dibenzodiazepines <i>via</i> alkoxycarbonylation and carboxamidation of <i>o</i>-isocyanodiaryl amines
A radical addition/cyclization reaction of o-isocyanodiaryl amines has been developed for the efficient synthesis of potentially bioactive dibenzo[b,e][1,4]diazepine-11-carboxylates and dibenzo[b,e][1,4]diazepine-11-carboxamides.
Tetrabutylammonium Chloride-Induced Cascade Radical Addition/Cyclization of <i>O</i>-Isocyanodiaryl Amines: A Novel Protocol for the Synthesis of 11-Trifluoromethylated Dibenzodiazepines
A straightforward protocol for the synthesis of 11-trifluoromethylated dibenzodiazepines has been developed via TBAC-induced trifluoromethylation/cyclization of o-isocyanodiaryl amines using Togni’s reagent as the trifluoromethyl source. This is the first report on the one-step construction of CF3-containing dibenzodiazepine drug skeletons. Additionally, a series of 11-trifluoromethylated dibenzodiazepines
Provided is a new class of phosphorescent emitters. The inventive emitters feature a benzimidazole phenoxide ligand, which is connected via “top linkers” to form novel tetradentate ligands. These phosphorescent emitters are Pt tetradentate complexes when used in OLEDs as emitters improves device external quantum efficiency (EQE) and operational lifetimes.
