Dehalogenation and Hydrogenation of Aromatic Compounds Catalyzed by Nanoparticles Generated from Rhodium Bis(imino)pyridine Complexes

Abstract: Chloro[2,6-bis{1-(phenyl)iminoethyl}pyridine]rhodium(I) complexes (RhCl(N,N,N); 1-11) have been prepared by reaction of the dimer [Rh(μ-Cl)(η 2 -C 2 H 4 ) 2 ] 2 with the corresponding nitrogen donor ligand. These complexes afford nanoparticles with a mean diameter of 1.5 ( 0.2 nm stabilized by the partially hydrogenated ligand, under 1 atm of hydrogen, in 2-propanol as solvent, at 60°C, and in the presence of K t BuO. Under a constant atmospheric pressure of hydrogen, the nanoparticles catalyze the dehalogenat… Show more

“…[28] At right, an octahedral (PDI)Rh complex featuring hydrogen bonding interactions between an apical chloride ligand and two amide arms. of either N,N-diisopropyl-1,2-ethanediamine or N,N-dimethyl-1,3-propanediamine afforded 2,6-(((CH 3 ) 2 -CH) 2 NCH 2 CH 2 N=C(CH 3 )) 2 [20,21,23,24,26,29,31,33] this approach to metallation was chosen as an entry point for investigating the coordination preferences of the newly prepared chelates. In this contribution, we detail our approach to this challenge with Hoping to establish the ideal chain length for κ 4 -or κ 5 -PDI coordination to a rhodium center, this study commenced with the synthesis of R PDI ligands featuring imine substituents that have an ethyl or propyl bridge to a remote tertiary amine donor.…”

“…Additionally, to probe the role of sterics in achieving κ 5 -N,N,N,N,N-rather than κ 4 -N,N,N,N-PDI chelation, the amine substituents were varied to include either methyl or isopropyl groups. [20,21,23,24,26,29,31,33] After stirring for 24 hours, evacuation of the solvent followed by washing of the solid with pentane allowed isolation of ( iPr 2 NEt PDI)RhCl (1-Cl) and ( Me 2 NPr PDI)RhCl (2-Cl), respectively [Equation (2)]. of either N,N-diisopropyl-1,2-ethanediamine or N,N-dimethyl-1,3-propanediamine afforded 2,6-(((CH 3 ) 2 -CH) 2 NCH 2 CH 2 N=C(CH 3 )) 2 [20,21,23,24,26,29,31,33] this approach to metallation was chosen as an entry point for investigating the coordination preferences of the newly prepared chelates.…”

“…Cyclohexylamines are commonly produced by hydrogenating the corresponding aniline derivative . The reaction is catalyzed by iridium, nickel, rhodium, and ruthenium compounds. Alternative synthesis strategies comprise the hydroamination of alkenes and the reductive amination of phenols to substituted cyclohexylamines .…”
