The Reaction of Bis(η 5 ‐Cyclopentadienyl)(1,2,3‐triphenyltriphosphane‐1,3‐diyl)zirconium(IV) , , with Ethyl Diazoacetate (Cp = η 5 ‐C 5 H 5 ) The reaction of bis(η 5 ‐cyclopentadienyl) (1,2,3‐triphenyltriphosphane‐1,3‐diyl)zirconium(IV), ( 1 ), with ethyl diazoacetate leads to insertion into both ZrP bonds with formation of ( 2 ), which contains the novel 1,2,3‐triphenyltriphosphane‐1,3‐bishydrazonido(2 –) ligand. The 31 P‐NMR spectrum shows that only the meso isomer of the P 3 Ph 3 fragment is present in solution. The crystal structure analysis shows this, too, as well as the η 2 ‐bonding mode of both N,N′ units to the zirconium atom.
