Treatment of dialkylketoximes with dichloroethane and KOH-DMSO results in the formation of alkylpyrroles in 31-61percent yields.In addition, the corresponding 1-vinylpyrroles are formed simultaneously in yields up to 18percent.The corresponding 1,2-bis(alkylideneiminoxy)ethanes are obtained as side products in the reaction; they result from nucleophilic displacement of chlorine atoms by oximate anions.
