Abstract:

Phosphaalkenyliron complex (h5-C5Me5)(CO)2FeP:C(SiMe3)2 (C5H5 = cyclopentadienyl) reacts with sulfur ylide Me2S(O):CH2 to give the h3-phosphallyliron complex I with a syn configuration in the organophosphorus ligand. In PhMe at 40 Deg I isomerizes to the corresponding anti configured complex (II). Structure and configuration of I-II were elucidated by spectroscopic methods (IR, 1H, 13C, 31P NMR, and MS) and by x-ray crystallog.
