Abstract

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