Fig. 5: Gas-phase production of sodium 2-methyl-butane-2,3-diolate)−3-ium (P4, m/z 147) by collision activation of sodiated acetone (R1, m/z 81).
From: Demethylation C–C coupling reaction facilitated by the repulsive Coulomb force between two cations
a Route 1 for demethylation C–C coupling reaction through a direct mechanism. b Route 2 for ion/molecule reaction by a two-step mechanism.
