The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

The syntheses and characterization of three new mixed sandwich complexes involving crown thioether ligands and Group 8 metal ions are reported. These complexes are: [Ru(C5H5)(9S3)]PF6 (1), [Ru(C5H5)(10S3)]PF6 (2) and [Fe(C5H5)(IOSS)]PF6 (3), where 9S3 = 1,4,7-trithiacyclononane and 10S3 = 1,4,7-trithiacyclodecane. All three complexes have been characterized by single-crystal X-ray crystallography, and all structures show an octahedral metal center with facially coordinated carbocyclic and macrocyclic ligands. The average M-S bond lengths in 1, 2 and 3 are 2.289(2), 2.331(2) and 2.1823(7) A, respectively, and these are shorter than the M-S bond lengths in the corresponding bis 9S3 and 10S3 complexes. We propose that this distance decrease is caused by enhanced metal-thioether pi bonding due to the strong sigma-donating ability of the Cp ligand. All structures are confirmed in solution via 1H- and 13C-NMR spectroscopy. Cyclic voltammetric studies on the three heteroleptic complexes show E1/2 values that are intermediate between those of the corresponding homoleptic hexakis(thioether) complexes and metallocenes. This electrochemical behavior is also consistent with the relative sigma-donating and pi-accepting abilities of the Cp and trithioether ligands.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8
