Reaction of one equivalent of the complexes [FeCp*(CO)2PnCl2] (Pn=P, As, Sb) with tetramethylcyclopentadienyllithium afforded compounds [FeCp*(CO)2Pn(Cl)(C5Me4H)}]. Dehydrochlorination by means of tert-butyllithium led to decomposition. Only in the case of the phosphorus compound was evidence for the initial formation of a phosphaalkene given by 31P NMR spectroscopy. Similarly treatment of equimolar amounts
