Case Study

Preparation of Iron-Diphosphine Complexes from Iron(II) Chloride for Catalytic Suzuki-Miyaura Coupling

Hatakeyama, Takuji, et al. Journal of the American Chemical Society, 2010, 132.31, 10674-10676.

The transition-metal-catalyzed cross-coupling reaction of organoboron compounds, known as Suzuki-Miyaura coupling, is one of the most prevalent organic synthetic reactions for the production of functional molecules, such as drug intermediates and organic electronic materials. In the presence of iron(II) chloride-diphosphine complexes and magnesium bromide, lithium arylborates react with primary and secondary alkyl halides to give the corresponding coupling products in good to excellent yields.
Iron(II) chloride-diphosphine complexes
· The iron(II) chloride-diphosphine complexes bear one o-phenylene-tethered diphosphine ligand possessing bulky substituents at the 3 and 5 positions of the diphenylphoshino groups.
· The bulky substituents were expected to introduce peripheral steric bulk around the iron center, preventing the formation of coordinatively saturated octahedral iron complexes.
