Sulfur and nitrogen half-mustard compounds lose their aggressive properties when the chlorine atom is replaced by a carbonate moiety. The anchimeric effect of the novel mustard carbonate analogues is investigated. The reaction follows first-order kinetics, does not need any base, and occurs with -OH, -NH and acidic -CH nucleophiles. Most of these molecules are unexplored and might provide a novel strategy for the preparation of compounds previously not easily accessible. Copyright

Basicity, nucleophilicity, and nucleofugality in the elimination-substitution reactions of β-phenylmercaptoethyl phenolates in DMSO-ethanol media
Kinetic studies have been performed on the base-promoted 1,2-elimination reactions of a series of β-phenylmercaptoethyl phenolates with potassium ethoxide in EtOH-DMSO media, yielding phenyl vinyl sulfide.The E2 mechanism was indicated by the absence of H
