SDS of cas: 147700-62-7. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (3aR,8aR)-2,2-Dimethyl-4,4,6,8,8-pentaphenyltetrahydro-[1,3]dioxolo[4,5-e][1,3,2]dioxaphosphepine, is researched, Molecular C37H33O4P, CAS is 147700-62-7, about Scope and Mechanism of the Pt-Catalyzed Enantioselective Diboration of Monosubstituted Alkenes. Author is Coombs, John R.; Haeffner, Fredrik; Kliman, Laura T.; Morken, James P..
The Pt-catalyzed enantioselective diboration of terminal alkenes can be accomplished in an enantioselective fashion in the presence of chiral phosphonite ligands. Optimal procedures and the substrate scope of this transformation are fully investigated. Reaction progress kinetic anal. and kinetic isotope effects suggest that the stereodefining step in the catalytic cycle is olefin migratory insertion into a Pt-B bond. D. functional theory anal., combined with other exptl. data, suggests that the insertion reaction positions platinum at the internal carbon of the substrate. A stereochem. model for this reaction is advanced that is in line both with these features and with the crystal structure of a Pt-ligand complex.
