Abstract
In methanol 4-methoxy-3,5-dinitrobenzaldehyde is in equilibrium with its hemiacetal formed by solvent addition to the carbonyl group. 1H N.m.r. measurements give the value of the equilibrium constant, KS, for hemiacetal formation as 8. In the presence of methoxide ions a Meisenheimer complex is formed by base addition to the parent aldehyde. Visible spectral measurements allow the determination of the value of 210 l mol–1 for K1, the thermodynamic equilibrium constant for Meisenheimer complex formation.
