(2,2-Dichlorovinyl)ferrocene

The title compound, [Fe(C5H5)(C7H5Cl2)], represents a versatile building block for the preparation of π-conjugated redox-active compounds or polymetallic organometallic systems due to the presence of the electrochemically active ferrocenyl unit. It is therefore a potential starting material for the preperation of the corresponding alkyne. In the crystal, the alkenyl unit and the cyclopentadienide ring are almost parallel, with an angle between the best planes of only 10.6 (4)°.
