• The ring opening reactions of six known or new 2,2-dichlorocyclopropyl phenyl sulfides have been carried out with potassium <I>t</I>-butoxide in <I>t</I> butyl alcohol and with pyridine. The products were enynes, butadienes, allenes and, as minor products, α,β-unsaturated aldehydes containing the phenylmercapto group. Reaction of a mixture of <I>cis</I>- and <I>trans</I>-1,1-dichloro-2-methyl-3-phenylmercaptocyclopropane (<B>2</B>) with pyridine gave unchanged <I>trans</I>-isomer. This apparent selectivity is explained on the basis of the steric effects for ring opening.
