Reactivity studies of (η6-arene)ruthenium dimeric complexes towards pyrazoles: isolation of amidines, bis pyrazoles and chloro bridged pyrazole complexes

Spectral, structural and DFT studies of platinum group metal 3,6-bis(2-pyridyl)-4-phenylpyridazine complexes and their ligand bonding modes

“…This is not the case with ruthenium complexes having the g 6 -p-i PrC 6 H 4 Me and g 6 -C 6 H 6 coligands, where Ru-L Ph bonding occurs in type-A fashion. Similar results for other complexes (based on reactivity studies) were observed earlier in our research group, where complexes containing the hexamethylbenzene co-ligand contrast clearly with those containing the g 6 -p-i PrC 6 H 4 Me and g 6 -C 6 H 6 ligands [41,42]. respectively.…”

An experimental–theoretical approach to the kinetics and mechanism of Michael type addition: α,β-Unsaturated tungsten Fischer carbene complex as the substrate

“…The alkynyl Fischer tungsten carbene complex A and 3-methyl-5-phenylpyrazole B were prepared and purified as described elsewhere [19,20]. The samples were dissolved in CDCl 3 for the NMR measurements, with the initial concentrations of A and B both as 0.04 mol L À1 .…”

Mono and dinuclear half-sandwich platinum group metal complexes bearing pyrazolyl-pyrimidine ligands: Syntheses and structural studies

“…In recent years, we have been carrying out arene ruthenium complexation reactions with a variety of nitrogen-based ligands [31][32][33][34][35][36] including pyridyl-pyridazine and pyrazolyl-pyridazine ligands. Ruthenium complexes of these types of nitrogen-based ligands have a capacity to function as catalysts for the oxidation of water to oxygen [37][38][39].…”
