Compound: Diphenyl-2-pyridylphosphine, is researched, Molecular C17H14NP, CAS is 37943-90-1, about Palladium-catalysed alkyne alkoxycarbonylation with P,N-chelating ligands revisited: a density functional theory study. Author is Ahmad, Shahbaz; Lockett, Ashley; Shuttleworth, Timothy A.; Miles-Hobbs, Alexandra M.; Pringle, Paul G.; Buhl, Michael.
A revised in situ base mechanism of alkyne alkoxycarbonylation via a Pd catalyst with hemilabile P,N-ligands (PyPPh2, Py = 2-pyridyl) 2-(diphenylphosphanyl)-4-methoxypyridine, 2-chloro-6-(diphenylphosphanyl)pyridine has been fully characterized at the B3PW91-D3/PCM level of d. functional theory. Key intermediates on this route are acryloyl and η3-propen-1-oyl complexes that readily undergo methanolysis. With two hemilabile P,N-ligands and one or both of them protonated, the overall computed barrier is 16.8 kcal mol-1. This new mechanism is consistent with all of the exptl. data relating to substituent effects on relative reaction rates and branched/linear selectivities, including new results on the methoxycarbonylation of phenylacetylene using (4-Me2N-Py)PPh2 and (6-Cl-Py)PPh2 ligands. This ligand is found to decrease catalytic activity over PyPPh2, thus invalidating a formerly characterized in situ base mechanism.
