An efficient, scalable synthesis of ferrocenylphosphine and dichloroferrocenylphosphine

Abstract

A new synthetic route to FcPH₂ and FcPCl₂ (Fc = ferrocenyl) is presented. This method avoids the challenging monolithiation of ferrocene, as well as any tedious purification steps. All reactions are high yielding and easily conducted on a relatively large scale, using economical and commercially available synthetic precursors.
