Chalcogen-Atom Abstraction Reactions of a Di-Iron Imidophosphorane Complex

Reaction of the complexes [Fe2(2-NP(pip)3)2(NP(pip)3)2] (1-Fe) and [Co2(2-NP(pip)3)2(NP(pip)3)2] (1-Co), where [NP(pip)3]1– is tris(piperidinyl)imidophosphorane, with nitrous oxide, S8, or Se0 result in divergent reactivity. With nitrous oxide, 1-Fe forms [Fe2(2-O)(2-NP(pip)3)2(NP(pip)3)2] (2-Fe),...
