Synthesis and photophysical properties of 7-(diethylamino)-3-(4-(arylethynyl)phenyl)-2H-chromen-2-ones as strong fluorescent materials

3-(4-(Arylethynyl)phenyl)-7-(diethylamino)-2H-chromen-2-ones 1a?1d were synthesized by Pd/Cu-catalyzed Sonogashira cross-coupling reactions. After the structural properties were examined by the X-ray crystal analysis, their photophysical properties including fluorescence properties in solid states were systematically studied. It was revealed that the pyrenyl derivative 1d showed high fluorescence quantum yield (ΦF = 0.87) in a THF solution, and that the phenyl derivative 1a exhibited an intense fluorescence (Φsolid = 0.15) even in a solid state. According to the TDDFT calculations, the HOMOs of compounds 1a and 1b are mainly located on the 3-(4-(arylethynyl)phenyl)-7-(diethylamino)-2H-chromen-2-one moieties, whereas on the aryl moieties for 1c and 1d. The electrochemical studies revealed that the compounds 1a and 1b underwent reversible 1e? oxidations.

Highly regioselective α-arylation of coumarins via palladium-catalyzed C-H activation/desulfitative coupling

A novel regioselective α-arylation of coumarins with readily available arenesulfonyl chlorides and sodium arenesulfinates via palladium-catalyzed direct C-H functionalizations under mild reaction conditions is described. This protocol presents an unexpected and highly regio-controlled arylation of coumarins at C-3 to construct interesting 3-arylcoumarins with fascinating biological and fluorescent properties. The regioselectivity observed is in sharp contrast with that expected for the Heck reactions. Copyright
