When 9-thienothienylfluoren-9-ol derivatives were ground together with DDQ then exposed to methanol vapor, solvolysis occurred to yield 9-methoxyfluorenes via the generation of a radical cation by solid-state single-electron transfer.
suggested by the ESR spectrum. The mechanism involving the collapse of the radical cation to generate a proton, which acts as a catalyst to afford the carbocation, was deduced based on the electrochemical oxidation of the substrate in solution. The propagation of the substitutionreaction in the solid state has been shown for the carbocation upon contact with methanol vapor. The crystalline inclusion
