摘要：

The compound [Ph2N3C2(C3F7)(2)]HgCH3 was synthesized from Na[Ph2N3C2(C3F7)(2)] and CH3HgCl. In solution, it exists as a mixture of two isomers that interconvert slowly on the NMR time scale. Both isomers feature a eta(1)-Ph2N3C2(C3F7)(2) ligand. In the asymmetrical one, the CH3Hg group is bonded to one of the two terminal nitrogen atoms. In the more stable symmetrical isomer, [PhN=C(C3F7)](2)NHgCH3, 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 CH3Hg shift reaction were obtained by DNMR spectroscopy. F-19 NMR spectra were analyzed. A metallotropic rearrangement was not observed in [Ph2N3C2(C3F7)(2)]AuPPh3.
