Although silver is a second-row transition metal, it is often treated as an “honorary” first-row metal due to its low cost and propensity for single-electron redox chemistry, and redox catalysis with well-defined silver complexes is under-developed. This work investigates reactive, high-valent silver intermediates in silver-catalyzed nitrene transfer reactions, with an eye towards the possibility of dinuclear redox cooperation. We describe the synthesis, isolation, and characterization of reactive silver(II) complexes with potential relevance to nitrene transfer catalysis, via spectroscopy and X-ray crystallography. In addition, we report the investigation of solution-phase structures of silver(I) and silver(II) complexes, using extended X-ray absorption fine structure (EXAFS) analysis.
