Application of 791-28-6, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 791-28-6, Name is Triphenylphosphine oxide, SMILES is O=P(C1=CC=CC=C1)(C2=CC=CC=C2)C3=CC=CC=C3, belongs to chiral-phosphine-ligands compound. In a article, author is Bagi, Peter, introduce new discover of the category.
The preparation and application of optically active organophosphorus compounds
Racemic acyclic phosphine oxides were separated into their enantiomers applying classical resolution methods based on complexation with chiral host molecules. The preparation of chloro-3-phospholenium chlorides was elaborated by the reaction of 3-phospholene oxides with oxalyl chloride. The cyclic chlorophosphonium salts were key intermediates, as they could be converted to the corresponding 3-phospholene boranes. Moreover, these reactive intermediates could be reacted with chiral alcohols, which enabled us to develop a dynamic resolution of 3-phospholene oxides based on the formation of covalent diastereomeric intermediates. P-Stereogenic phosphine oxide pre-catalysts showed promising enantioselectivity values in a catalytic Wittig-reaction. [GRAPHICS] .
Application of 791-28-6, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 791-28-6 is helpful to your research.
