Arylpalladium complexes monophosphine ligands

Steric properties of the ligand have a more pronounced effect on the rate of reductive elimination. Arylpalladium phenoxide complexes containing a stericaUy hindered monophosphine P(Fc)(I-Bu)2 (Fc = ferrocenyl) underwent reductive elimination of diaryl ethers, even when the palladium-bound aryl group was unactivated, as shown in Eq. Arylpalladium phenoxide intermediates containing P(t-Bu)3 as ligand under-...
