Methylphenylpropargyl-(3-phenylpropargyl)-ammonium bromide salts are cyclized almost quantitatively under base-catalysis conditions with the formation of 2-methyl-2-phenylbenz[f]isoindolinium bromide. The allyl analog is subject to rearrangement-deco

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 simultaneo
