Abstract
The previously unknown bis-2-benzopyrylium salts and 2-benzopyrylium salts containing an alkylcarboxy group were synthesized by the acylation of some alkoxy-substituted deoxybenzoins and phenylacetones with dibasic aliphatic acids in polyphosphoric acid. The effect of the structure of the dicarboxylic acid on the structure of the reaction products was followed. The IR spectra of the synthesized salts are presented.
