Abstract
Current information is inadequate to predict the rates at which polyhalogenated alkanes undergo dehydrohalogenation reactions under environmental conditions, forming olefins that are frequently more toxic and more recalcitrant than the products of substitution reactions. To permit evaluation of the relative importance of different potential transformation products, qualitative relationships between structure and reactivity via substitution and dehydrohalogenation pathways are reviewed. Parameters needed for preliminary estimates of dehydrohalogenation reactivity for new compounds are provided. In addition, information is furnished concerning the design of future experiments in buffered aqueous solution.
