Evidence for the generation of aromatic cationic systems in the excited state. Photochemical solvolysis of fluoren-9-ol
Abstract
Photolysis of Fluoren-9-ol (1) in aqueous methanol solution results in efficient formation of 9-methoxyfluorene (2); the driving force for the photosolvolysis is believed to be the formation of an aromatic 4π cationic system in the excited-state.
