Improved synthesis of pyrylium salts from either substituted benzoic acids or their methyl esters, and substituted acetophenone is reported en route to the synthesis of 2,4-diarylfurans. The mechanism involved in the formation of the pyrylium salt using these starting materials is proposed.
据报道,在合成2,4-二芳基呋喃的过程中,由取代的苯甲酸或其甲基酯和取代的苯乙酮改进了吡喃鎓盐的合成。提出了使用这些原料形成吡啶盐的机理。
