Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 6372-42-5, Name is Cyclohexyldiphenylphosphine, SMILES is C1CCC(CC1)P(C1=CC=CC=C1)C1=CC=CC=C1, belongs to chiral-phosphine-ligands compound. In a document, author is Mao, Biming, introduce the new discover, Quality Control of Cyclohexyldiphenylphosphine.
Phosphine-Catalyzed [4+2] Annulation of Allenoate with Sulfamate-Derived Cyclic ‘mines: A Reaction Mode Involving gamma ‘-Carbon of alpha-Substituted Allenoate
A phosphine-catalyzed [4 + 2] cycloaddition of cyclic alpha-substituted allenoates with sulfamate-derived cyclic imines has been reported. Using dibenzylphenylphosphine as the nucleophilic catalyst, the reaction worked efficiently to yield various fused multicyclic heterocyclic compounds in high yields with excellent diastereoselectivities. It undergoes a new reaction mode involving gamma’-carbon of alpha-substituted allenoate.
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 6372-42-5 is helpful to your research. Quality Control of Cyclohexyldiphenylphosphine.
