Abstract

[(η-²C₅H₅)Fe(PPh₃)(CO)(Mthoxycarbene)]⁺ complexes, prepared either from terminal acetylenes or from the corresponding acyl complexes, are stereoselectively deprotonated, as evidenced by the crystal structure of (Z)-[(η⁵-C₅H₅)Fe(PPh₃)(CO)(COMeCHMe)], to (Z)-methoxyvinyl complexes which can be stereoselectively alkylated under mild conditions to give elaborated acyl complexes.
