Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 6224-63-1, Name is Tri-m-tolylphosphine, molecular formula is C21H21P, belongs to chiral-phosphine-ligands compound. In a document, author is Kotani, Shunsuke, introduce the new discover, COA of Formula: C21H21P.
Phosphine Oxide-Catalyzed Asymmetric Aldol Reactions and Double Aldol Reactions
Chiral phosphine oxides successfully catalyze asymmetric cross-aldol reactions of various carbonyl compounds in a highly enantioselective manner. The phosphine oxide catalysts coordinate to chlorosilanes to form chiral hypervalent silicon complexes in situ, which activate both aldol donors and acceptors, thus realizing cross-aldol reactions between a ketone and an aldehyde, between two aldehydes, between two ketones, and of 2,6-diketones. The use of phosphine oxide catalysis can be further extended to achieve the first catalytic enantioselective double aldol reactions, realizing one-pot stereoselective construction of up to four stereogenic centers.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 6224-63-1. COA of Formula: C21H21P.
