Abstract

The synthetic utility of bis(trimethylstannyl)alkynyls in the preparation of Group 8 metal (Fe²⁺, Ru²⁺, Os²⁺) σ-acetylide monomeric, M(DEPE)₂(CCC₆H₅)₂ (M Fe²⁺, Ru²⁺; DEPE = 1,2-bis(diethylphosphino)ethane), Ru(DPPE)₂ (CCC₆H₅)₂ (DPPE = 1,2-bis(diphenylphosphino)ethane), Os(DPPM)₂(CCC₆H₅) ₂ (DPPM = 1,2-bis(diphenylphosphino)methane) and polymeric, [M(DEPE)₂CCRCC]_n (M Fe²⁺, Ru²⁺), [Os(DPPM)₂CCRCC-]_n (R = p-C₆H₄- C₆H₄-p, p-C6H4, p-C₆H₂(CH₃)₂) complexes is demonstrated. The linear arrangement of the acetylenic units around octahedral metal centres is confirmed by a single crystal X-ray structure determination of the model complex trans-[Ru(DPPE) ₂(CCC₆H₅)₂].
