Abstract

When 2-(1-arylethylidene)malononitriles act upon 3-nitrobenzofurans in the presence of triethylamine, the furan ring opens and triethylammonium 2-aryl-1,1-dicyano-5-nitropenta-2,4-dien-1-ides are formed. The obtained salts containing the chromophoric 1,1-dicyanopentadienide fragment are of interest as anionic polymethine dyes.
