Common 3-deoxyanthocyanidins and original dicationic flavylium- benzopyrylium derivatives are easily and efficiently synthesized through reactions between the corresponding phenols and aryl ethynyl ketones in the presence of aqueous hexafluorophosphoric acid. The mechanism of the reaction is discussed and two competitive pathways are consistent with our results. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Base-catalysed addition of phenols to terephthaloylacetylene yields trans-1, 4-bis(3-aryloxy-2-propenoyl)benzenes 10-16 only. However, under identical conditions alcohols do not give the addition products; only polycyclotrimerisation of terephthaloylacety
