Abstract

p-Bis[3-alkyl-(2-propenyl)ammonio-1-propynyl]benzene dibromide is subject to two-stage cyclization and rearrangament‒decomposition under base catalysis conditions. The possibility of a two-stage cyclization of m-bis[3-dialkyl-(2-propynyl)ammonio-1-propynyl]benzene dibromide with the formation of benzo[5,6:5',6'-а,с]di(2,2-dialkylisoindolinium) dibromide in quantitative yield has been shown.
