We report a one-step synthesis of the phosphine, PPh2iC3F7 from commercially available precursors. The stereoelectronic properties of the phosphine were probed by coordination to transition metals. Mo(CO)5PPh2iC3F7 was synthesised and the synthesis and structure of trans-PtCl2(PPh2iC3F7)2 are described. PPh2iC3F7 was found to be a bulky electron-withdrawing ligand.
