Molecular asymmetry and restricted rotation in transition-metal complexes: silylmethyl and silylacetyl derivatives of the π-cyclopentadienyliron carbonyl phosphine system

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).
