Abstract

The oxidative addition of 4-substituted iodobenzenes on Pd0-PMe3 complexes has been studied at the BP86 level of theory including dispersion correction and solvation effect, with tetrahydrofuran as solvent. The bisphosphine pathway was found to be barrierless, whereas the monophosphine route is hampered by the high dissociation energy of trimethylphosphine. The reaction free energy of this step shows linear correlation with the Hammett constants of the para substituents with the most electron withdrawing groups being the most exergonic.

The present scientific contribution is dedicated to the 650th anniversary of the foundation of the University of Pécs, Hungary
