Stereospecific reactions of the “M(C6F5)2” (M Pd or Pt synthons towards cis-dithiolato complexes
摘要:
Complexes of the general formula cis-[M(SC6F5)2L2] (M = Ni, Pd, or Pt; L2 = dppm [bis(diphenylphosphino)methane], dppe [1,2-bis(diphenylphosphino)ethane], or 2PPh3) were synthesized by the reaction (1: 2) between the corresponding cis-[MCl2L2] and Tl(SC6F5). When treated with cis-[M(C6F5)2(THF)2] (M = Pd or Pt; THF = OC4H8) they yield geminal homo- or hetero-binuclear compounds, which were characterized by IR, NMR and mass spectroscopy.

Mononuclear palladium and platinum complexes of the type M(ER)(2)((PP)-P-boolean AND) [M = Pd or Pt; ER = SPh, SC6H4Cl-4, SC6H4Me-4, SC6F5, SePh, TeC6H4OEt-4; (PP)-P-boolean AND = dppm or dppe] have been prepared and their ability to form dinuclear metal species has been demonstrated. All complexes have been characterised by multinuclear magnetic resonance (H-1, C-13, Se-77, Pt-195) spectral data. The effects of phosphine ligands and organochalcogenides are reflected in the Se-77 and Pt-195 NMR shifts. The shielding of Pt-195 NMR chemical shifts has been interpreted in terms of their binding ability to platinum. The structures of two derivatives, namely [Pd(SC6F5)(2)(dppe)] and [Pd(SePh)(2)(dppe)], have been established by X-ray crystallography. The palladium atom in each of the monomeric structures exists in a square planar geometry. (C) 1999 Elsevier Science S.A. All rights reserved.

By reacting Tl(SC6F5) with halide containing complexes of palladium(II) or platinum(II), mono- or binuclear compounds with terminal and/or bridging pentafluorothiophenolato groups can be obtained. Treatment of the latter ones with triphenylphosphine causes bridge-cleavage affording cis-mononuclear compounds.
