We will report two new proton-relay ligand platforms, diphenylphosphinoaniline and diphenylphosphine oxide. An amido neutral μ-hydride, [HFe2(pdt)(CO)2(PNH)(PNH2)], was afforded via reaction of Fe2(pdt)(CO)6 with two equiv of diphenylphosphinoaniline (PNH2). We will describe the proton exchange behavior of this amido-amine as well as its conversion to the diamine [HFe2(pdt)(CO)2(PNH2)2]+ and the diamide [HFe2(pdt)(CO)2(PNH)2]-1. We will also describe another μ-hydride species, confirmed via NMR spectroscopy, with the nominal formula Fe2(edt)(CO)3(HOPPh2)3. As in the Fe2-PNH2 case, these Fe2-phosphinous acid complexes display rich acid-base behavior.
