Palladium-Catalyzed Cross-Coupling Reactions of Organosilanols: I. New Methods That Employ Alkynylsilanols and Bissilyl Reagents. II. Mechanistic Analysis of the Cross-Coupling of Aryldimethylsilanolates

Abstract

587 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2007.Mechanistic investigations of the palladium-catalyzed cross-coupling of aryldimethylsilanolates demonstrated that transmetalation proceeds directly from an arylpalladium(II) silanolate intermediate without external activation. Arylpalladium(II) silanolate complexes bearing phosphine ligands were isolated and characterized. These complexes produce biaryl products via ligand dissociation and transmetalation.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
