Application of 78871-05-3, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.78871-05-3, Name is Di(naphthalen-2-yl)phosphine oxide, molecular formula is C20H15OP. In a patent, introducing its new discovery.
Palladium-Catalyzed Cascade C?O Cleavage and C?H Alkenylation of Phosphinyl Allenes: An Expeditious Approach to 3-Alkenyl Benzo[b]phosphole Oxides
A phosphine oxide-directed intramolecular cyclization of phosphinyl allenes is established for the first time. The palladium-catalyzed intramolecular cyclization provides an unprecedented cascade C?O cleavage and direct C?H alkenylation toward novel 3-alkenyl benzo[b]phosphole oxides, along with broad group tolerance and high regioselectivity. Control experiments and mechanistic studies explain the sequential performance of C(sp3)-OAr cleavage and P=O directed C(sp2)-H activation. (Figure presented.).
