The reaction of α-chloro ketones with ethane-, propane-, and butanethiols leads to the corresponding (alkylthio)alkenes.Noncyclic chloro ketones give a mixture of the cis and trans isomers of di(alkylthio)alkenes, while the reaction of α-chloropinacoline leads only to the cis isomers of the 1,2-di(alkylthio)-3,3-dimethyl-1-butene.The mechanism of the reaction of α-chloro ketones with thiols includes nucleophilic substitution of the chlorine with the formation of alkylthio ketones.The addition of a further molecule leads to the corresponding intermediate alkylthio a cohols, which are easily dehydrated to the final products under the acidic conditions.
