Abstract
I.r. and n.m.r. spectral data for new σ-silyl-acetyl- and σ-silylmethyl-π-cyclopentadienyliron carbonyl phosphine complexes are discussed and indicate that it should be possible to synthesize and resolve optically active organo-iron complexes from the general asymmetric system σ-R-π-C5H5FeCO(L).
