Abstract
Abstract Ionization rates of para-substituted triphenylmethyl (trityl) acetates, benzoates, and para-nitrobenzoates have been determined in aqueous acetonitrile and aqueous acetone at 25 C. Conventional and stopped-flow techniques have been used to evaluate rate constants ranging from 1.38× 10− 5 to 2.15× 10 2 s− 1 by conductimetry and photospectrometry methods. The varying stabilities of the differently substituted tritylium ions account for a ...
