INSERTION OF CLPPH(2) INTO A TA-H BOND - SYNTHESIS AND STRUCTURE OF THE FIRST PHOSPHIDO DERIVATIVE OF TANTALOCENE
- Ph2PCl easily inserts into the Ta-H bond of Cp2TaH3 affording an ionic complex [Cp2TaH2(HPPh2)]Cl (4). This species was deprotonated to give the first phosphido-substituted tantalocene complex Cp2TaH2PPh2 (5), which was characterized by NMR spectroscopy and X-ray crystallography. Thermal decomposition of 5 as well as its reaction with HPPh2 was studied. © 1995 American Chemical Society.
