Tricarbonyl(η5-2-methyl-3-methoxycyclohexadienyl)iron(1 +) PF6(1 −) (2) undergoes regioselective alkylation by (−)-1-phenylethylamine and by phosphoramide derivatives of carboxylic acid esters. The diastereomeric 1-phenylethylamine adducts were separated and reconverted into (+)-2 and (−)-2 by treatment with TFA. Resolved complexes such as 2 have stereochemical properties, arising from the presence
