Notizen:
The use of trifluoroacetic anhydride as an NMR solvent for sugars has been explored. Dissolution of carbohydrates in this solvent is accompanied by trifluoroacetylation at the hydroxyl groups. Esterification results in downfield shifts of the sugar protons yielding very well resolved 1H NMR spectra. The use of trifluoroacetic anhydride in the analysis of complex systems is exemplified.
