Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The chloromethylation of benzo-1,4-dioxane in acetic acid in presence of SnCl4, SbCl3, ZnCl2, and SbCl5 catalysts was investigated. The activation energy of the process was found to be 19.6 kcal/mole. The reaction is zero order in chloride ion and first order in the Hammett acidity function. In excess HCl the reaction is described by a second-order equation. The relative activities of the methyl chlorides in the chloromethylation of benzo-1,4-dioxane were determined.
