Abstract
It was shown that dialkylpropargyl/3-(p-chlorophenyl)-2,3-dichloroallyl/ammonium salts in an aqueous alkali medium undergo cyclization-dehydrochlorination to give chlorine-containing benzisoindolinium salts. When the ammonium salt contains simultaneously 3-phenyl (or vinyl)propargyl and 3-(p-chlorophenyl)-2,3-dichloroallyl groups, only the latter enters into the cyclization as the diene fragment.
