Understanding Reactive Sulfur Species through P/S Synergy.

ABSTRACT: We investigated the differential oxidative and nucleophilic chemistry of reactive sulfur and oxygen anions (SSNO^-, SNO^-, NO₂^-, S₄^2-, and HS^-) using the simple reducing electrophile PPh₂Cl. In the case of SSNO^- reacting with PPh₂Cl, a complex mixture of mono and diphosphorus products is formed exclusively in the P(V) oxidation state. We found that the phosphine stoichiometry dictates selectivity for oxidation to P=S/P=O products or transformation to P₂ species. Interestingly, only chalcogen atoms are incorporated into the phosphorus products and, instead, nitrogen is released in the form of NO gas. Finally, we demonstrate that more reducing anions (S₄^2-
