Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 4045-44-7, Name is 1,2,3,4,5-Pentamethylcyclopenta-1,3-diene, SMILES is CC1C(C)=C(C)C(C)=C1C, belongs to catalyst-ligand compound. In a document, author is Zippel, Christoph, introduce the new discover, Name: 1,2,3,4,5-Pentamethylcyclopenta-1,3-diene.
Multigram-Scale Kinetic Resolution of 4-Acetyl[2.2]Paracyclophane via Ru-Catalyzed Enantioselective Hydrogenation: Accessing [2.2]Paracyclophanes with Planar and Central Chirality
[2.2]Paracyclophane (PCP) derivatives have been promising platforms to study the element of planar chirality and through-space electronic communications in pi-stacked molecular systems. To access enantiomerically pure derivatives thereof, a kinetic resolution of 4-acetyl[2.2]-PCP employing a ruthenium-catalyzed enantioselective hydrogenation process was developed. This method can be performed on a multigram-scale and gives access to enantiomerically pure derivatives with planar and central chirality of (R-p)-4-acetyl-PCP (>= 97% ee, 43%) and (Sp,S)-PCP derivatives (>= 97% ee, 46%), which are useful intermediates for the synthesis of sterically demanding PCP-based ligand/catalyst systems and chiral synthons for engineering cyclophane-based chiroptical materials.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4045-44-7 is helpful to your research. Name: 1,2,3,4,5-Pentamethylcyclopenta-1,3-diene.
