Routes to Succinimide and Pyridine-Substituted Pt(II) Complexes: An Unexpected Pattern of Reactivity

Z-type ligands remove electron density from the metal center, providing tunable electronic control over metal complexes. Based on previous work with silyl-palladium cations, we hypothesize that a mismatch of hard Pt(IV) with a soft iodide ligand may act as a source of iodonium cation, a reactivity profile uncharacteristic of Pt-I bonds. To investigate this, Pt(II) iodide complexes bound to a series of bidentate ligands with varying bite angles and stereoelectronic properties will be reacted with known iodonium sources. Addition of N-iodosuccinimide (NIS) and bis(pyridine)iodonium tetrafluoroborate to Pt(II) starting materials leads to a mono-succinimide/pyridine substituted Pt(II) product with an I3- ligand at one equivalent, and a bis-succinimide/pyridine complex at three equivalents. Unexpectedly, this trend holds true despite changing the ligand identity.Bachelor of Scienc
