甲硅烷基芳基三氟甲磺酸酯，CsF，水杨酸酯的反应提供了一个通用和有效的方法来制备生物有趣的吨酮和噻吨酮。这种化学反应可能是通过串联的分子间亲核偶联和随后的分子内亲电环化进行的。
The reaction of silylaryl triflates, CsF, and salicylates affords a general and efficient way to prepare biologically interesting xanthones and thioxanthones. This chemistry presumably proceeds by a tandem intermolecular nucleophilic coupling and subsequent intramolecular electrophilic cyclization.
