Phosphinite based palladacycles show extremely high activity
in the Suzuki coupling of both sterically hindered and electronically
deactivated aryl bromides, especially in the presence of one equivalent of
free ligand.

phosphinite ligands PR2(OAr) (R = Ph, iPr), their simple complexes with palladium(II) and their palladacycliccomplexes has been investigated. The crystal structure of one of the palladacycliccomplexes, [Pd(μ2-Cl)κ2-P,C-PiPr2(OC6H2-2,4-tBu2)}2], has been determined. The palladacycliccomplexes show extremely high activity in the Suzuki coupling of aryl bromide substrates with phenylboronic acid and can
