Redox-Induced Reversible PP Bond Formation to Generate an Organometallic σ4λ4-1,2-Biphosphane Dication

Twice the fun: Dimeric FeII diphosphonium bis(alkynyl) complexes are formed by oxidation of the corresponding FeII alkynyl phosphine complexes. The structure of these organometallic diphosphonium salts and their monomeric precursors were established by X‐ray crystallography. The PP bond can be clea...

Zusammenfassung:	Twice the fun: Dimeric FeII diphosphonium bis(alkynyl) complexes are formed by oxidation of the corresponding FeII alkynyl phosphine complexes. The structure of these organometallic diphosphonium salts and their monomeric precursors were established by X‐ray crystallography. The PP bond can be cleaved by two‐electron reduction to regenerate the monomers.
