Abstract 1-(Phenylthio)cyclopropylcarbinyl alcohols are converted to 2-alkyl-1, 1-di(phenylthio)cyclobutane derivatives upon treatment with 48% HBr and ZnBr2. Heating with copper triflate and Hunig's base gave 2-alkyl-1-(phenylthio)cyclobutenes which were pyrolyzed to 3-alkyl-2-di-(phenylthio)-1,3-butadienes in moderate to good yield.
