In contrast to the reversible photochemistry of the 2,2′-substituted bixanthenylidenes (1a-f), the photocyclization of 2,2′-diacyl bixanthenylidenes (1g-j) reveals an irreversible process where the initial cyclic intermediate C(E) can undergo a rapid [1,1
Synthesis of xanthones, thioxanthones, and acridones by the coupling of arynes and substituted benzoates

The reaction of silylaryl triflates, CsF, and ortho-heteroatom-substituted benzoates affords a general and efficient way to prepare biologically interesting xanthones, thioxanthones, and acridones. This chemistry presumably proceeds by a tandem intermolecular nucleophilic coupling of the benzoate with an aryne and a subsequent intramolecular electrophilic cyclization.

(Chemical Equation Presented) 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.
