Abstract

The compound [Ph ₂N ₃C ₂(C ₃F ₇) ₂]HgCH ₃ was synthesized from Na[Ph ₂N ₃C ₂(C ₃F ₇) ₂] and CH _3- HgCl. In solution, it exists as a mixture of two isomers that interconvert slowly on the NMR time scale. Both isomers feature a η ¹-Ph ₂N ₃C ₂(C ₃F ₇₎₂ ligand. In the asymmetrical one, the CH ₃Hg group is bonded to one of the two terminal nitrogen atoms. In the more stable symmetrical isomer, [PhN=C(C ₃F ₇)] ₂NHgCH ₃, mercury is attached to the central nitrogen atom. It is this isomer that crystallizes and that was characterized by X-ray diffraction. Thermodynamic parameters for the CH ₃Hg shift reaction were obtained by DNMR spectroscopy. ¹⁹F NMR spectra were analyzed. A metallotropic rearrangement was not observed in [Ph ₂N ₃C ₂(C ₃F ₇) ₂]AuPPh ₃.
