Ligand Electronic Effect on Reductive Elimination of Biphenyl from <i>ci</i>s-[Pt(Ph)<sub>2</sub>(diphosphine)] Complexes Bearing Electron-Poor Diphosphine: Correlation Study between Experimental and Theoretical Results
The reductiveelimination 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 using 1,2-bis(diphenylphosphino)ethane (dppe) and seven of its fluoroaromatic analogues as ancillary diphosphine ligands. The fastest reaction rate corresponded to 3, bearing
The reaction of a nickelalactone with dppm, resulting in the formation of a stable binuclear Ni(I) complex with an acrylate, a Ph2P− and a dppm bridge, models a key step in the formation of acrylic acid from CO2 and ethylene.
