The eta(6)-1,3,5-triphosphabenzene transition metal complexes 12a,b, 14, an
d 16 have been synthesized for the first time by the displacement of eta(6)
-arena ligands (toluene, benzene and naphthalene) with 2,4,6-tri-tert-butyl
-1,3,5-triphosphabenzene (9). The new complexes have been fully characteriz
ed by a combination of elemental analysis, mass spectrometry, and H-1-, C-1
3- and P-31-NMR spectroscopy.
