as Ph3PS. Calculated reaction profiles reveal outer‐sphere reactivity for uranium(V) but inner‐sphere mechanisms for uranium(VI); despite the wide divergence of products the initial activation of CE2 follows mechanistically related pathways, providing insight into the factors of uranium oxidation state, chalcogen, and NCE groups that govern the subsequent divergent redox reactions that include common
