Synthesis of Bis(η 5 ‐cylopentadienyl)(1,2,3‐triphenyltriphosphane‐1,3‐diyl)zirconium(IV) and ‐hafnium(IV) , (M = Zr, Hf), and Structure of the Hafnocene Derivative The reaction of [MCp 2 Cl 2 ] (M = Zr, Hf; Cp = η 5 ‐C 5 H 5 ) with [LiPHPh · 2 THF] and of [ZrCp 2 Me 2 ] with PH 2 Ph leads to ( 1a , M = Zr; 1b , M = Hf). The crystal structure of 1b shows that only one diastereomer is present [( R ) at P(1), ( S ) at P(3)] and that the HfP 3 metallacycle is virtually coplanar.
