Synthetic Route of 78871-05-3. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 78871-05-3, Name is Di(naphthalen-2-yl)phosphine oxide. In a document type is Patent, introducing its new discovery.
Chiral unsymmetric diphosphine compound and transition metal complex containing the same as ligand
A novel chiral unsymmetric diphosphine compound of formula (I): STR1 wherein Ar1 and Ar2, which are different from each other, each represent a substituted or unsubstituted phenyl group, a substituted or unsubstituted naphthyl group, a pyridyl group, a quinolyl group, an isoquinolyl group, a furfuryl group, a benzofurfuryl group, a thienyl group, or a benzothienyl group, and a transition metal complex containing the diphosphine compound as a ligand. The complex catalyzes various asymmetric synthesis reactions, e.g., asymmetric hydrogenation or asymmetric hydrosilylation, exhibiting excellent performance in selectivity, conversion and catalytic activity, to provide a product of desired absolute configuration at high optical purity and in high yield.
