Abstract
AbstractA 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 η1‐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′‐CO2Me‐3′,4′‐Me2PC4‐FeCp*)‐(η5‐Me2PC4)FeCp*] 10.
