Synthesis of Pd(II) 1-alkylperimidine complexes as efficient catalysts for suzuki reactions involving arylchlorides

“…The NMR and IR values are similar to those found for N-coordinated metal complexes [18][19][20][21][22][23][24]. The NMR and IR values are similar to those found for N-coordinated metal complexes [18][19][20][21][22][23][24].…”

Imidazole Based Ruthenium(IV) Complexes as Highly Efficient Bifunctional Catalysts for the Redox Isomerization of Allylic Alcohols in Aqueous Medium: Water as Cooperating Ligand

“…We have investigated the catalytic activity of ruthenium­(IV) [Ru­(η 3 :η 3 -C 10 H 16 )­Cl 2 (L)] (L = imidazole ( 1a ), benzimidazole ( 1b ), N -methylimidazole ( 1c )) and ruthenium­(II) [Ru­(η 6 -arene)­Cl 2 L] complexes ( 2a – c ) for comparative purposes. All of them have been synthesized in good yield from the commercially available dimeric precursors [{Ru­(η 3 :η 3 -C 10 H 16 )­Cl 2 } 2 ] and [{RuCl­(μ-Cl)­(η 6 -arene)} 2 ] by reaction with the appropriate ligand following procedures reported in the literature for analogous 1,2-azoles , and for 2b , c , (Scheme ).…”

“…Solvents were dried by standard methods and distilled under nitrogen before use. All reagents were from suppliers and used without further purification with the exception of compounds [{Ru­(η 3 :η 3 -C 10 H 16 )­(μ-Cl)­Cl} 2 ] ( 1 ), − [{Ru­(η 6 -arene)­(μ-Cl)­Cl} 2 ] (arene = C 6 H 6 , p -cymene, C 6 Me 6 ), , [Ru­(η 6 - p -cymene)­Cl 2 (benzimidazole)] ( 2b ) , (conductivity in water, 20 °C: 173 Ω –1 cm 2 mol –1 ), [Ru­(η 6 -C 6 Me 6 )­Cl 2 (benzimidazole)] ( 2c ) , (conductivity in water, 20 °C: 180 Ω –1 cm 2 mol –1 ), which were prepared by following the methods reported in the literature. Infrared spectra were recorded on a Perkin-Elmer 1720-XFT spectrometer.…”
