The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium, is researched, Molecular C18H28ClRu, CAS is 92390-26-6, about Solution Thermochemical and Structural Studies of Ligand Substitution of N-Pyrrolyl-Substituted Phosphine Ligands in the Cp’Ru(PR3)2Cl (Cp’ = η5-C5H5 and η5-C5Me5) Systems, the main research direction is crystal structure ruthenium cyclopentadienyl pyrrolylphosphine complex; mol structure ruthenium cyclopentadienyl pyrrolylphosphine complex; enthalpy substitution pyrrolylphosphine ruthenium cyclopentadienyl COD; bond length strength ruthenium pyrrolylphosphine complex; pyrrolidinylphosphine substitution ruthenium cyclopentadienyl COD complex.Name: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium.
The enthalpies of reaction of Cp’Ru(COD)Cl (Cp’ = η5-C5H5 and η5-C5Me5; COD = cyclooctadiene) with N-pyrrolyl-substituted monodentate tertiary phosphine ligands, giving Cp’Ru(PR3)2Cl (PR3 = P(NC4H4)3; P(NC4H4)2Ph, P(NC4H4)Ph2, P(NC4H8)3), were measured by anaerobic solution calorimetry in THF at 30.0°. These reactions are rapid and quant. Structural studies were carried out on five complexes in this series, and a discussion of bond length-bond strength relations is presented. The measured reaction enthalpies span a range of 5 kcal/mol. This series of ligands include some of the most weakly bound phosphines calorimetrically studied within these two related organometallic systems. Relative importance of phosphine steric vs. electronic ligand parameters is more closely examined in terms of the presented quant. thermochem. and structural information. Comparisons with enthalpy data in related organometallic systems are also presented.
As far as I know, this compound(92390-26-6)Name: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
