Chemistry, like all the natural sciences, SDS of cas: 791-28-6, begins with the direct observation of nature¡ª in this case, of matter.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 document, author is Teo, Ronald Hong Xiang, introduce the new discover.
Asymmetric Catalytic 1,2-Dihydrophosphination of Secondary 1,2-Diphosphines – Direct Access to Free P*- and P*,C*-Diphosphines
A 1,2-dihydrophosphination of bis(phenylphosphino)ethane with a wide range of activated olefins was achieved in a catalytic manner with enantiomeric and diastereomeric excess of up to >99% and 44% respectively. The protocol can be extended to selected substrates leading to free P- and C-chiral 1,2-diphosphines. The synthesized ligands can also undergo direct complexation onto palladium affording complexes with complete retention of stereo-integrity.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 791-28-6. SDS of cas: 791-28-6.
