Mixed-ligand ruthenium(II) complex with 2,2′-bipyridine and 1,10-phenanthroline-3,8-dicarboxylic acid the composition [Ru(phen-C)(bpy)2]Cl2·5H2O (bpy = 2,2′-bipyridine, phen-C 1,10-phenantroline-3,8-dicarboxylic acid) has been synthesized characterized by spectral data. The tested as photocatalyst in aerobic oxidation reactions, including transformation of arylboronic acids to phenols, primary ...
hemistry 2017 been widely used to construct important families of target molecules, aryl ethers, suldes and sulfoxides. Traditionally, these reactions are carried out in organic solvents (e.g., THF, CH3CN, DMSO, and DMF), which may cause potential health, safety, and waste disposal issues. Therefore, transition-metalfree C–O and C–S coupling reactions under greener conditions are desirable, es...
Thioether-containing poly(para-phenylene-ethynylene) (PPE) copolymers show a strong fluorescence turn-on response when exposed to oxidants in solution as a result of the selective conversion of thioether substituents into sulfoxides and sulfones. We propose that the increase in fluorescence quantum yield (Phi(F)) upon oxidation is the result of both an increase in the rate of fluorescence (k(F)...
