Abstract The kinetics of hydrolysis (deamination or dealcoholation) of tritylamines and 2, 2, 2- trifluoroethyl ethers and their corresponding 4-methoxy, 4, 4′-dimethoxy-, and 4, 4′, 4 ″- trimethoxy-substituted analogues in aqueous solutions up to 3.5 mol· dm− 3 in strong acid have been investigated at constant ionic strength. In all cases, acid-catalysed hydrolytic processes have been observed, with finite reactivity at [H 3 O+]= 0. Strong upward ...
