Methanol Solutions

The proton magnetic resonance spectra of boron trifluoride – methanol solutions in sulfur dioxide, with methanol in excess, are interpreted in terms of equilibria between methanol, methanol·BF3, and (methanol)2·BF3. The two methyl peaks observed in the spectra at low temperatures may be attributed to methyl groups in free and complexed methanol (i.e. methanol in which the oxygen is coordinated by BF3).
