摘要：

Rate constants have been measured for the reactions of hydroxide ion with the 2-OMe, 2-Me, 2-Cl, 2-Br, 2-CF3, 2-NO2 and 2-OH derivatives of Brilliant Green. The rates of hydrolysis, which are generally slower than those of the correspondingly 3- and 4-substituted derivatives, are influenced primarily by steric factors. Thermodynamic parameters ΔH≠ and ΔS≠ have been obtained for each dye and an isokinetic relationship has been established. The 2-hydroxy derivative of Brilliant Green showed anomalous behaviour for which an explanation is offered. © 1990.
