Vibrational circular dichroism of 3-(trifluoroacetyl)-camphor and its interaction with chiral amines

Vibrational circular dichroism (VCD) spectroscopy and density functional theory (DFT) calculations are used to investigate the keto-enol equilibrium of 3-(trifluoroacetyl)-camphor (TFC) and to study the interaction of TFC with chiral aminesin deuterated Chloroform. It is shown that the VCD spectra o...

description Vibrational circular dichroism (VCD) spectroscopy and density functional theory (DFT) calculations are used to investigate the keto-enol equilibrium of 3-(trifluoroacetyl)-camphor (TFC) and to study the interaction of TFC with chiral aminesin deuterated Chloroform. It is shown that the VCD spectra of the enol- and keto forms of TFC can clearly be distinguished and that the enol form is favored. By deprotonationof the TFC enol with chiral amines, no indication of a mutual diasteriomeric influenceon the VCD spectra induced by transfer of stereochemical information between the chiralionic species is found, neither experimentally nor theoretically.
