Abstract
The reaction of salicylaldehydes with benzyne prepared from o-trimethylsilyphenyl triflate and CsF gave xanthenes and xanthones. When the reaction was carried out under basic conditions, 9-hydroxyxanthenes (xanthols) were obtained in good yields.
摘要
水杨醛与由邻三甲基硅基苯基三氟甲磺酸酯和氟化铯制备的苯炔反应生成呫吨和呫吨酮。当反应在碱性条件下进行时，可高产率得到9-羟基呫吨（呫吨醇）。
