Методика

A mixture of 2.1 g (3 mmol) of 1-butyl-2-(2-{3-[2-(1-butyl-1H-benzo[cd]indol-2-ylidene)ethylidene]-2-phenylcyclohex-1-en-1-yl)ethenyl)-benzo[cd]indol-1-ium tetrafluoroborate, 9.1 g (4.5 mmol) of sodium 1,1,3,3,3-pentafluoro-2-(pivaloyloxy)propanesulfonate aqueous solution, 20 g of water, and 50 g of methylene chloride was stirred overnight at room temperature, whereupon the organic layer was taken out. The organic layer was washed with water, concentrated in vacuum, combined with methyl isobutyl ketone, and concentrated in vacuum again. Diisopropyl ether was added to the residue for recrystallization. The crystal was collected and dried in vacuum, obtaining the target compound, 1-butyl-2-(2-{3-[2-(1-butyl-1H-benzo[cd]indol-2-ylidene)-ethylidene]-2-phenylcyclohex-1-en-1-yl)ethenyl)-benzo[cd]indol-1-ium 1,1,3,3,3-pentafluoro-2-(pivaloyloxy)-propanesulfonate. Brown crystal, 2.6 g, yield 93%.
