Styrene phenylation by non-activated bromobenzene (Heck reaction) in the presence of ligand-free catalytic systems based on PdCl2 proceeds under diffusional controlled regime. It was experimentally found that an increase in the agitation speed leads to an increase in the reaction rate, a substantial decrease of the time for attaining a product complete yield and gives rise to the extra high TOF (150,000 h(-1) in 50 min at 780 rpm).
