Synthesis, molecular structure and NMR spectroscopy of a transition-metal bifluoride complex: formation via C–F activation or reaction with Et3N·3HF
Abstract
The bifluoride complex,
trans-[Ru(dmpe)

by reaction of cis-[Ru(dmpe)

with fluoroarenes (C

and others) or by reaction with Et
3
N·3HF; its
solid-state structure, established crystallographically, reveals a
Ru(η
1
-FHF) moiety with a long Ru–F bond and an
F···F distance close to that in bifluoride salts,
while the presence of the same complex in solution is shown by
low-temperature NMR spectra.
