Two fluorescent cyclopalladated arylpyrazine complexes: synthesis, crystal structures and application in the double Suzuki coupling of N-heteroaryl halides with 1,4-benzenediboronic acid

Abstract Two 2-dicyclohexylphosphino-2',6'-dimethoxybiphenyl (Sphos) adducts of cyclopalladated arylpyrazine complexes have been synthesized and characterized. Additionally, the structures of both complexes were determined by single-crystal X-ray analysis

Impact of substituents on molecular properties and catalytic activities of trinuclear Ru macrocycles in water oxidation

Herein we report a broad series of new trinuclear supramolecular Ru(bda) macrocycles bearing different substituents at the axial or equatorial ligands which enabled investigation of substituent effects on the catalytic activities in chemical and photocatalytic water oxidation. Our detailed investigations revealed that the activities of these functionalized macrocycles in water oxidation are significantly affected by the position at which the substituents were introduced. Interestingly, this effect could not be explained based on the redox properties of the catalysts since these are not markedly influenced by the functionalization of the ligands. Instead, detailed investigations by X-ray crystal structure analysis and theoretical simulations showed that conformational changes imparted by the substituents are responsible for the variation of catalytic activities of the Ru macrocycles. For the first time, macrocyclic structure of this class of water oxidation catalysts is unequivocally confirmed and experimental indication for a hydrogen-bonded water network present in the cavity of the macrocycles is provided by crystal structure analysis. We ascribe the high catalytic efficiency of our Ru(bda) macrocycles to cooperative proton abstractions facilitated by such a network of preorganized water molecules in their cavity, which is reminiscent of catalytic activities of enzymes at active sites.

Palladium nanoparticles catalyzed Suzuki cross-coupling reactions in ambient conditions

An efficient pathway to synthesize biaryls and terphenyls through ligand-free palladium nanoparticles (PdNPs) catalyzed Suzuki cross-coupling reactions has been developed. Mild reaction conditions, high yields of desired products, absence of inert atmosphere and short reaction times are the notable features of this method.

Efficient synthesis of substituted terphenyls by Suzuki coupling reaction

The Suzuki cross-coupling reactions of phenyl-1,4-diboronic acid bis-pinacol ester with a range of aryl halides are reported. The reaction proceeded smoothly, even with sterically hindered aryl halides, to give symmetrical terphenyls often quantitatively.
