The synthesis of alkenyl-extended cyclohexadienyliron complexes is described and reactions are reported demonstrating that regio- and stereoselective functionalisation can be controlled by the judicious choice of nucleophile, alkali metal counterion and ligand set at iron. The crystal structures of tricarbonyl[(1,2,3,4,5-η)-1-(1′-methylethenyl)-4- methoxycyclohexadienyl]iron(1+) hexafluorophosphate(1-), tricarbonyl[(1,2,3,4,5-η)-1-(ethenyl-1′-phenyl)-4- methoxycyclohexadienyl]iron(1+) hexafluorophosphate(1-), (E)-dicarbonyl[(1,2,3,4,5-η)-1-(2′-methylethenyl)-4- methoxycyclohexadienyl]triphenylphosphineiron(1+) hexafluorophosphate(1-), tricarbonyl[methyl(2,3,4,5-η)-2-carbomethoxy-2-(4-methoxy-1-(1′- methylethenyl)cyclohexadien-1-yl)ethanoate]iron(0), are reported. The stereochemical course of a long-range relay of chirality controlled by the carbonyliron group is proven.
