[(η-<sup>2</sup>C5H5)Fe(PPh3)(CO)(Mthoxycarbene)]<sup>+</sup> complexes, prepared either from terminal acetylenes or from the corresponding acyl complexes, are stereoselectively deprotonated, as evidenced by the crystal structure of (Z)-[(η<sup>5</sup>-C5H5)Fe(PPh3)(CO)(COMe.dbd;CHMe)], to (Z)-methoxyvinyl complexes which can be stereoselectively alkylated under mild conditions to give elaborated acyl complexes.
