Deprotonated 1,2-diols and β-methoxyhydrins often eliminate ROH (R=H, Me) on collisional activation in the gas phase. These losses do not involve a negative ion pinacolrearrangement in acyclic systems in which there are no conformational restraints on the relative positions of the reacting groups. In the case of β-methoxyhydrins, labeling studies show that the product ion is formed by the losses of
