Development and Mechanistic Investigation of the Palladium-Catalyzed Alpha-Arylation of Aldehydes and N-Arylation of Ammonia
… developed. The catalyst generated from Pd[P(o-tol)3]2 and the alkylbisphophine CyPF-t-Bu is a highly active and selective catalyst for the coupling of ammonia with aryl chlorides, bromides, iodides, and sulfonates. The couplings of ammonia with this catalyst conducted with a solution of ammonia …

Palladium-catalyzed reactions of ammonia, carbon monoxide, and cyanide
… bromides and aryl iodides with 2 mol % of Pd[P(o-tol)3]2 and CyPF-t-Bu under 3 atm total of ammonia and carbon monoxide. The resting state of the catalyst was identified as the Pd(0) di-carbonyl complex (CyPF-t-Bu)Pd(CO)2, which dimerized to [(CyPF-t-Bu)2Pd2(μ-CO)] upon isolation. These complexes …

Late transition metal catalyzed C-N and C-C bond forming reactions
… for these transformations. Initially, P(o-tol)3 ligated palladium catalysts were investigated but gave way to systems that used chelating phosphine ligands which substantially expanded the scope of the catalytic amination methodology. Palladium catalyst systems based on BINAP …

Ligand design principles for perfecting stereoretention in Suzuki-Miyaura cross-coupling of unactivated CSP3 boronic acids
The strategy of building block-based, iterative synthesis has revolutionized the preparation of oligonucleotides and oligopeptides. However, small molecules possess greater structural diversity than these classes of macromolecules. The development of an iterative, building block-based synthetic …
