Abstract
Electron-withdrawing substituents (R(2) and R(3)) result in a remarkab le reduction in the rate coefficient for removal of the hydrogen-bonde d proton, from 2-alkyl-4-(R(2), R(3)-phenylazo) resorcinol monoanions by hydroxide ion such that the reaction can be followed by conventiona l spectrophotometry with t(1/2) in the range of minutes.
