常见的3-脱氧花青素和原始的二烷基黄-苯并吡啶衍生物在六氟磷酸水溶液存在下，通过相应的酚类与芳基乙基酮反应，可以容易、高效地合成。讨论了反应的机理，两种竞争途径与我们的结果一致。(C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim。，德国，2007)。
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. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim., Germany, 2007).
