A chiral racemic tris(phosphaferrocene) complex showing two bridging keto functionalities has been prepared diastereoselectively through the elaboration of a single 2,5‐diester‐substituted phosphaferrocene. The reaction profile involves the intervention of a single trinuclear complex, which contains two phosphametallocene units and an η 1 ‐coordinated phospholyl ligand 9 , whose organisation determines the stereochemistry of the final product. This complex evolves smoothly to give a chiral triphosphametallocene (±)‐( R *, R *)‐[2,5‐(2′‐CO 2 Me‐3′,4′‐Me 2 PC 4 ‐FeCp*)‐(η 5 ‐Me 2 PC 4 )FeCp*] 10 .
