摘要: Abstract We present a systematic study of the reverse-phase high performance liquid chromatography (HPLC) complexes containing an Fe 2 (CO) 6 unit bonded to variety organic chains, namely butatriene moiety R CCCCR , butadienyl fragment, RCCRRCCR (the ferroles), and ring-opened cyclopentadienone diradical, RCCRC(O)RCCR flyover bridges). Since shows almost identical conformation in all complexes, this enables us evaluate effect geometrical arrangement chains their substituents on chromatographic behaviour. Reverse-phase HPLC allows separation positional isomers ferroles bridges (R Me or Ph), but not cis / trans butatrienes H Me).
