| Abstract: | The 12‐membered‐ring metallacycles [mer‐Re{≡CCH=C(R)C≡C?}Cl(PMe2Ph)3)]2 (R=CMe3, 1‐adamantyl), which are organometallic analogues of antiaromatic octadehydro[12]annulene, are prepared by heating the methyl carbyne complexes mer‐Re{≡CCH=C(R)C≡CH}(CH3)Cl(PMe2Ph)3. An intermolecular σ‐bond metathesis between the Re?CH3 bond and the acetylenic C?H bond is proposed for their formation. |
