In a Article，once mentioned of 4254-15-3
Exchange etherification of dicarbonylcyclopentadienyl(eta2-ethyl vinyl ether)iron tetrafluoroborate (4) with optically active primary and secondary alcohols yields a mixture of diastereomeric cations.These isomers are in rapid equilibrium at room temperature.The most favorable equilibrium ratio of such diastereomers (4:1) is achieved with (+)- or (-)-menthol, and the absolute configuration of the predominant diastereomer, formed with (-)-menthol, has been determined.Optically active dicarbonylcyclopentadienyl (eta2-olefin)iron tetrafluoroborate may also be prepared from optically active epoxides.A study of the circular dichroism of these optically active complexes, together with those prepared earlier from the dioxene-iron complex (1), has been carried out and a mechanism by which asymmetry is induced at the achiral metal center is proposed.These observations provide the basis for a quadrant rule relating the sign of the Cotton effect near 450 nm and the absolute configuration of the olefin-iron complex.
This is the end of this tutorial post, and I hope it has helped your research about 4254-15-3 . COA of Formula: C3H8O2
