Stereocontrolled tandem alkylations: Michael additions and subsequent alkylations of α,β-unsaturated acyl ligands bound to [(η5-C5H5)Fe(CO)(PPh3)]

Abstract

α,β-Unsaturated acyl complexes of [(η⁵-C₅H₅)Fe(CO)(PPh₃)] can be prepared by the Peterson olefination reaction and are found to undergo tandem stereoselective Michael additions and subsequent methylations which result in the stereocontrolled synthesis of α- and β-substituted iron acyl complexes.
