Zusammenfassung: | 9,10-Diazophenanthrone undergoes WOLFF rearrangement in alcoholic solvents and yields esters of 9-fluorene carboxylic acid. By flash light photolysis four intermediates could be detected. Kinetic measurements showed that the ketene formed by photolysis reacts with the solvent to give a cyclopentadienylic carbanion, which is protonated. A carbene or an oxirene intermediate could not be found. |
