Abstract
Abstract Kinetic studies on the hydrolytic decomposition of 4-[[4-(dimethylamino)phenyl]imino]-2,5-cyclohexadien-1-one [phenol blue (PB)], 4-[(4-hydroxyphenyl)imino]-2,5-cyclohexadien-1-one [indophenol (IP)], and 4-[[4-(dimethylamino)phenyl]imino]-naphthalen-1-one [indophenol blue, (IPB)] in HCl solutions are consistent with nucleophilic addition of water to the protonated imine functionality. The reactivity increases in the order PB∼IP
