Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1663-45-2, is researched, Molecular C26H24P2, about Designing and synthesis of phosphine derivatives of Ru3(CO)12 – Studies on catalytic isomerization of 1-alkenes, the main research direction is trinuclear ruthenium carbonyl ethanebisphosphino complex catalyst preparation crystal structure; isomerization catalyst trinuclear ruthenium carbonyl ethanebisphosphino complex.Category: chiral-nitrogen-ligands.
A comparative investigation on the isomerization reactions of 1-alkenes to their corresponding 2-alkenes catalyzed Ru3(CO)12 (1), Ru3(CO)9(PEt3)3 (2) and Ru3(CO)10(dppe) (3), (dppe = 1,2-bis(diphenylphosphino)ethane) is described. Both the complexes of types 2 and 3 were characterized by all anal. and spectroscopic data. The mol. structure of 2 was confirmed by single-crystal x-ray anal. The nature of phosphine ligands plays an important role in the isomerization of 1-alkenes. When the chelated diphosphine was used, the internal isomerization reaction by [Ru3(CO)10(dppe)] (3) is completed relatively in less time compared to other derivatives As per the DFT calculations, the observed reaction rate for the alkene isomerization may be explained based on the relative stability of 1, 2, and 3. The CO abstraction step is highly feasible in 3, the least stable among the three, thus the reaction occurs at the highest rate. Due to the increased relative stability from 2 to 1, the reaction requires more time at elevated temperatures and the rate decreases as a consequence.
As far as I know, this compound(1663-45-2)Category: chiral-nitrogen-ligands can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
