Abstract:The kinetics of the ethanolysis of three triphenylmethyl chlorides, the 4-nitro, 4,4′-dinitro, and 4,4′,4″-trinitrophenylmethyl compounds, have been studied. The effect of change in substrate and solvent composition on the activation parameters, ΔH≠ and ΔS≠, has been determined. For these compounds, ΔH≠ appears to be controlled by substrate structure while ΔS≠varies predominantly with solvent composition.The attempted reaction of pyridine with 4,4′,4″-trinitrophenylmethyl chloride to form the quaternary ammoni… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
