Synthesis and coordination chemistry of fluorinated phosphonic acids
摘要:
Phosphonic acids [(HO)(2)P(O)C2H4CnF2n+1] (n = 4, 6) and [(HO)(2)P(O)C6H4-4-CnF2n+1] (n = 0, 1, 6) have been prepared in good yields. Deprotonation and reaction with cis-[PtCl2(PPh3)(2)] affords fluorinated platinum complexes which have been characterised by elemental analysis, mass spectrometry, IR and NMR spectroscopies. The structures of [Pt{O2P(O)C6H4-4-F}(PPh3)(2)], [Pt{O2P(O)C6H4-4-CF3}(PPh3)(2)] and [Pt{O2P(O)C2H4C6F13}(PPh3)(2)] have been determined by single crystal X-ray diffraction. (C) 2009 Elsevier B.V.
