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
