  Polar trifluoromethylation reations: syntheses of trifluoromethyl gallium, indium, and thallium compounds. The mechanism of polar trifluoromethyl group transfer

  摘要：

  The reactions of Cd(CF3)2 complexes with GaCl3, InCl3, and TlX3 (X: Cl, OCOCH3, OCOCF3) in aprotic basic solvents have given the compounds Ga(CF3)3.dmf, Ga(CF3)2Cl.dmf, [Cd(CH3CN)2]-[Ga(CF3)4]2, In(CF3)3.2CH3CN, In(CF3)2Cl.dmf, and Tl(CF3)3.2dmf, which have been characterized by NMR spectroscopy, mass spectrometry, vibrational spectroscopy, and elemental analysis. All trifluoromethylmetal halides formed as intermediates were detected by F-19 NMR spectroscopy. The dependence of the chemical shifts and the coupling constants 2J(Tl-203/205-F-19) on the number of CF3-groups bound to the central atom provides unambiguous evidence for the formular of trifluoromethyl gallates and thallates and the existence of the [Ga(CF3)4]--anion has been confirmed by Ga-71 NMR spectroscopy.A mechanism for successful polar trifluoromethyl group transfer is discussed on the basis of Pearson's HSAB concept and the results of conductivity measurements.

• Solvent influence on trifluoromethylation reactions with Cd(CF3)2: one-pot synthesis of trifluoromethyl iron complexes

  ligand-exchange reaction is observed, yielding trifluoromethyl iron acetonitrile complexes, while carbonyl complexes are obtained in ethers. The compound [Fe(CO)4(CF3)2] has been prepared in 65% yield, and its 19F n.m.r., i.r., Raman, mass, and Mössbauer spectra recorded. The advantage of observing the 13C satellites in the 19F n.m.r. spectra for the analysis of trifluoromethyl metal compounds is established. If
