The aluminium enolate derived from (η5-C5H5)Fe(CO)(PPh3)(COMe) undergoes stereoselective aldol condensations with aldehydes to generate β-hydroxy acyl complexes which yield β-hydroxyacids on decomplexation.

The aluminium enolate derived from the iron acetyl complex [(η5-C5H5Fe(CO)(PPh3)COCH3], in contrast to the lithium enolate, undergoes highly stereoselective aldol reactions with aldehydes to generate RR,SS-β-hydroxyacyl complexes which on decomplexation liberate β-hydroxy acids or esters. Determination of the molecular structure of RR,SS-[η5-C5H5)Fe(CO)(PPh3)(COCH2CH(OH)CH2CH3] allowed assignment of
