Pd NPs, obtained in situ from imidazole complexes Pd(im) 2 Cl 2 (im ¼ methylimidazole, butylimidazole), efficiently catalyze the carbonylative Suzuki coupling in water at 80 C and 1 atm of CO. In the catalytic system, used without any additional ligands, differently substituted diaryl ketones were obtained with yields of up to 100% in 1 h. Under slightly modified conditions, Pd NPs catalyze the alkoxycarbonylation of iodobenzenes to esters with high yield.a Reaction conditions: 80 C, [Pd] 1 mol%, PhI (1 mmol), PhB(OH) 2 (1.2 mmol), CO (1 atm), Na 2 CO 3 (3 mmol), water 5 mL, 1 h, [Hg]/[Pd] 200.

Ruthenium complexes [RuCl2L2] were prepared by treating [RuCl2(p‐cymene)]2 with structurally similar N‐(2‐(diphenylphosphino)benzylidene)‐3‐methylpyridin‐2‐amine, 4‐(2‐(diphenylphosphino)benzylideneamino)‐3‐methylphenol and 4‐(2‐(2‐(diphenylphosphino)benzylideneamino)ethyl)phenol refluxed in toluene. These complexes were used as catalysts for the transfer hydrogenation of acetophenones in 2‐propanol and for the direct hydrogenation of styrenes under hydrogen pressure. The results of the catalytic studies provide evidence that these complexes function as excellent catalysts for hydrogenation and transfer hydrogenation. Copyright © 2014 John Wiley & Sons, Ltd.

Pd/DNA catalysts were prepared in a mixed H2O/EtOH solvent using palladium precursors, Pd(OAc)2 and PdCl2, in different dosages and salmon fish sperm DNA. As prepared, the Pd/DNA contained Pd(II) and Pd(0) nanoparticles of various sizes and morphologies, depending on the preparation method. Pd/DNA efficiently catalyzed the Suzuki–Miyaura cross-coupling of various aryl bromides with phenylboronic acids. The catalyst was recovered by simple phase separation and then reused in seven consecutive cycles with a high activity.
