Kohlenwasserstoffverbrückte Metallkomplexe, XXII1) Addition von anionischen Fischer‐Carben‐Komplexen an koordinierte ungesättigte Kohlenwasserstoffe unter C – C‐Kupplung

Hydrocarbon‐Bridged Metal Complexes, XXII1). – Addition of Anionic Fischer Carbene Complexes to Coordinated Unsaturated Hydrocarbons with C – C Coupling The addition of [(OC)5MC(OMe)CH2]– (M = Cr,W) to the cationic complexes [(OC)5Re(C2H4)]+ and [(OC)3M' (λ7‐C7H7)]+ (M' = Cr, Mo) affords the bimetallic hydrocarbon‐bridged complexes (OC)5M = C(OMe)CH2CH2CH2Re(CO)5 (1) and (OC)5M = C(OMe)CH2C7H7 – λ6 – M'(CO)3 (2), respectively. The structures of 1a and 2d have been determined by X‐ray diffraction.
