Ligand electronic effect on reductive elimination of biphenyl from ci s-[Pt(Ph)2(diphosphine)] complexes bearing electron-poor diphosphine: Correlation study between experimental and theoretical results

The reductive elimination of biphenyl from cis-[Pt(Ph) 2(diphosphine)] (3) was studied to clarify the electronic effects of diphosphine ligands on the reaction. Reaction kinetic data were evaluated in d8-toluene within 80-110 °C usin

Ligand influence on the electronic properties of some bis(tertiary phosphine)-substituted chromium and molybdenum carbonyls: Cyclic voltammetry and infrared spectroscopy of M(CO)4R2PCH2CH2PR2

The bidentate phosphines R2PCH2CH2PR2 (R = F, Cl, C6F5, CH3O, C6H5, CH3, and c-C6H11) and their respective chromium and molybdenum complexes were synthesized to provide a wide range of electronic effects at the metal center. Cyclic voltammetry and infrared spectroscopy were used to determine relative charge density at the metal center. As determined by cyclic voltammetry the π-acceptor strength of the ligands R2PCH2CH2PR2 decreases in the order R = F > Cl > C6F5 > CH3O > C6H5 > CH3 > c-C6H11. A linear correlation between k(CO)trans and the value E1/2 = (Ea + Ec)/2 was found for the series M(CO)6 and M(CO)4R2PCH2CH2PR2 (where M = Cr or Mo and R = F, Cl, C6F5, CH3O, and C6H5). The complexes containing the ligands (CH3)2PCH2CH2P(CH3) 2 and (c-C6H11)2PCH2CH 2P(c-C6H11)2 do not fall on this line but lie below it. The existence of these two groups of phosphines is argued to reflect the difference in the π-acceptor capabilities of the ligands.
