Synthesis and characterisation of new pyrazole–phosphinite ligands and their ruthenium(II) arene complexes

Synthesis, molecular and electronic structures of half-sandwich ruthenium(II) complexes with pyrimidine-based ligands

“…The energy decomposition analysis of the complexes, based on the work of Morokuma [28][29][30], and the extended transition state (ETS) partitioning scheme of Ziegler [31,32] have been carried out using the ADF program (Release 2008) [33] at the level of B3LYP/TZP. The binding energy of each compound was calculated as the difference between the energy of the geometry optimized (2) 0.93 2.80 3.267(4) 112.6 C(7)-H (7)…Cl (1) complexes and the energies of the optimized free ligands Hmtp and pyrimidine and the [(C 6 H 6 )RuCl 2 ] fragment.…”

Synthetic, Spectral, Structural, and Catalytic Aspects of Some Piano‐Stool Complexes Containing 2‐(2‐Diphenylphosphanylethyl)pyridine

“…[9][10][11][12] Furthermore, the ruthenium complex [(η 5 -C 5 H 5 )-Ru(PPh 3 ) 2 Cl] and the dimeric complexes [{(η 6 -arene)Ru(µ-Cl)Cl} 2 ] (η 6 arene = C 6 H 6 , C 10 H 14 , and C 6 Me 6 ) and [{(η 5 -C 5 Me 5 )M(µ-Cl)Cl} 2 ] (M = Rh or Ir) play a vital role in organometallic chemistry. [13][14][15][16] While the reactivity of these precursors with a variety of ligands has been reported, its reactivity with PPh 2 EtPy is yet to be explored. It is well established that simple phosphane-containing ruthenium, rhodium, and iridium complexes acts as active catalysts, particularly in presence of a base and incorporation of the η 5 -C 5 H 5 , η 5 -C 5 Me 5 , and η 6 -arene as spectator ligands in the complexes boosts enantioselectivity of the respective reactions.…”

New chiral phosphinite ligands with C2‐symmetric axis and their possible applications in Ru‐catalyzed asymmetric transfer hydrogenation

“…from clear orange to deep red, was attributed to the dimer cleavage most probably by the bis(phosphinite) ligand. [45] Ru{chloro ( [46,47] It is significant to remark that 31 P-{ 1 H} NMR signals of ligands and complexes do not differ significantly. [48] Elemental analyses of products 3 and 4 are consistent with the suggested molecular formulas.…”
