The air-stable tetranuclear coordination cluster [CuII2DyIII2L4(NO3)2(CH3CN)2]·2(CH3CN), which can be obtained in high yield, promotes the Suzuki coupling reaction of phenylboronic acid with substituted aryl halides under environmentally benign conditions.

An oxygen-bridged triarylamine polycyclic unit based tris-cyclometalated heteroleptic iridium(<scp>iii</scp>) complex: correlation between the structure and photophysical properties
436 ns), and the phosphorescence color can be tuned from green to orange. Electrochemical experiments and DFT calculations reveal that Ir–NO exhibits a high HOMO energy level and intraligand charge transfer (3ILCT) excitedstate properties, which is in contrast to the low HOMO energy level and metal-to-ligand charge transfer (3MLCT) excitedstate properties in Ir–N and Ir–O. This result can be attributed
2′‐bipyridine ligand with a larger torsion angle (12.70°) in comparison with those of Ir‐N (5.51°) and Ir‐O (8.11°). Unpredictably, both Ir‐N and Ir‐O show deep red emission in solution, whereas Ir‐NO exhibits no emission. However, all complexes show significant luminescence in their respective polystyrene (PS) films, and Ir‐NO displays a longer emission lifetime than those of Ir‐N and Ir‐O. DFT calculations
The present invention relates to heterocyclic derivatives as anti-inflammatory agents. The compounds of this invention can be useful, for inhibition and prevention of inflammation and associated pathologies including inflammatory and autoimmune diseases such as sepsis, rheumatoid arthritis, inflammatory bowel disease, type-1 diabetes, asthma, chronic obstructive pulmonary disorder, organ transplant rejection, acute coronary syndrome and psoriasis.
