Mechanisms of Nucleophilic Attack at Carbon-Nitrogen Double Bonds. The Solvolysis of Substituted Benzohydrazonoyl Halides in Aqueous Binary Mixtures

Abstract

Rate data for the solvolysis of a series of substituted benzohydrazonoyl halides in aqueous dioxan at 329 K and in aqueous ethanol and methanol at 303 K are presented. The products in the aqueous alcohols were measured by h.p.l.c ., and the selectivities determined. The data are used to support proposals about the mechanism of the reaction.
