Chalcogen-atom abstraction reactions of a Di-iron imidophosphorane complex

Abstract

Reaction of the complexes [Fe22-NP(pip)3)2(NP(pip)3)2] (1-Fe) and [Co22-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 results in divergent reactivity. With nitrous oxide, 1-Fe forms [Fe22-O)(μ2-NP(pip)3)2(NP(pip)3)2] (2-Fe), with a very short Fe3+–Fe3+ distance. Reactions of 1-Fe with S8 or Se0 result in the bridging, side-on coordination (μ-κ11-E22−) of the heavy chalcogens in complexes [Fe2(μ-κ11-E2)(μ2-NP(pip)3)2(NP(pip)3)2] (E = S, 3-Fe, or Se, 4-Fe). In all cases, the complex 1-Co is inert.
