Abstract

Neutral palladium(IV) complexes containing the bis(pyrazol-1-yl)borate ligand, PdMe3{(pz)2BH2}(L) [L=py-d5 (4), PMe2Ph (6)], are generated in solution by oxidative addition of iodomethane to [PdMe2{(pz)2BH2}]- at -70°C followed by addition of L; the Pd(IV) complexes reductively eliminate ethane above 0°C. Stable Pt(IV) analogues of 4 and 6 have been isolated, and comparison of NMR spectra for Pd(IV) and Pt(IV) species support structural assignments for the unstable Pd(IV) complexes. The complex PtMe3{(pz)2BH2}(py) (1a) has been characterised by X-ray diffraction, together with Pt(mq)Me2{(pz)2BH2} (2) (mq=8-methylquinolinyl); both complexes show a fac-PtC3 configuration for Pt(IV), and for 2 the Pt-N distances are ∼0.03 Å shorter than in the isostructural Pd(IV) complex. © 2002 Elsevier Science B.V.
