Opening 'Jaws': Functionalisation of the hexaphosphapentaprismane cage, (P6C4Bu4)-Bu-t, affording (X2P6C4Bu4)-Bu-t (X = Me, I), crystal and molecular structures of (X2P6C4Bu4)-Bu-t (X = Me, I) and [cis-(PtCl2Me2P6C4Bu4)-Bu-t]

摘要

The hexaphosphapentaprismane cage, (P6C4Bu4)-Bu-t ("Jaws"), can be readily opened by reaction with iodine at room temperature to afford the di-iodo derivative (I2P6C4Bu4)-Bu-t which can be converted to the dimethyl derivative (Me2P6C4Bu4)-Bu-t by treatment with LiMe. (Me2P6C4Bu4)-Bu-t behaves as a bidentate ligand towards PtCl2. The molecular structures of all the new compounds have been determined by P-31 and/or Pt-195 NMR spectroscopy and single crystal X-ray diffraction studies.
