Synthesis of Phenylferrocene in Supercritical Carbon Dioxide

Abstract:

The environmentally benign Suzuki cross-coupling reaction was developed by using ScCO₂ (Supercritical CO₂) instead of traditionally organic solvent. In the paper the compound phenylferrocene was synthesized by the Suzuki cross-coupling reaction of iodoferrocene and phenylboronic acids in ScCO₂/PEG (polyethylene glycol) with excellent yield ratio in the presence of ligand-free Pd/C catalyst and K₂CO₃.1.5H₂O as base. The Pd/C catalyst can be reused by simply washing sequence and CO₂ can be recycled after depressurization. The catalytic reaction conditions were optimized in the reaction using ScCO₂ as solvent.
