Development of Nonclassical Photoprecursors for Rh₂ Nitrenes.

ABSTRACT: Characterization of reactive intermediates in C-H functionalization is challenging due to the fleeting lifetimes of these species. Synthetic photochemistry provides a strategy to generate post-turnover-limiting-step intermediates in catalysis under cryogenic conditions that enable characterization. We have a long-standing interest in the structure and reactivity of Rh₂ nitrene intermediates, which are implicated as transient intermediates in Rh₂-catalyzed C-H amination. Previously, we demonstrated that Rh₂ complexes bearing organic azide ligands can serve as solid-state and in crystallo photoprecursors in the synthesis of transient Rh₂ nitrenoids. Complementary solution-phase experiments have not been available due to the weak binding of m
