description

Aryl bromides can be coupled with phenylboronic acid in moderate to excellent yields using a transtetrakis(pyridine)dichloroiron(II) catalyst. The Suzuki–Miyaura reaction can be carried out under air in ethanol and aqueous ethanol with low catalyst loading. Addition of TBAB dramatically increases the yields in aqueous ethanol or in water. trans-Tetrakis(pyridine)dichloroiron(II) offers an environmental and less expensive method for the synthesis of biaryl compounds. This is the first example of an iron– pyridine catalyst for Suzuki cross-coupling.
