Complementary regioselection in nucleophile additions to cationic η5-cyclohexadienyl iron complexes
Abstract
1-Alkoxy and 1-acetoxy substituted tricarbonyl(η5-cyclohexadienyl)iron(1+) complexes undergo reactions with nucleophiles at opposite ends of the π-system in a reversal of regiocontrol that offers novel possibilities for complementary control strategies in applications in asymmetric synthesis, since the two series of complexes can be obtained from the same precursor.
