Related Products of 13440-07-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 13440-07-8, Name is Di(naphthalen-1-yl)phosphine oxide. In a document type is Article, introducing its new discovery.
The rhodium-catalyzed hydroformylation of vinyl acetate and related esters was carried out in the presence of chiral phosphine ligands of the DIOP type to give the corresponding optically active 2-(acyloxy)propanal, a precursor for the amino acid threonine.Ligand structure and the ligand/metal ratio were the primary factors controlling asymmetric induction; temperature, CO pressure, and solvent polarity had minor effects.The highest induction efficiencies, up to 51 percent ee, were obtained with the 5H-dibenzophospholyl derivative of DIOP (DIPHOL, 1e).
