METHOD FOR PRODUCING HYDROCARBON GROUP-SUBSTITUTED FLUORENONE

摘要

PROBLEM TO BE SOLVED: To provide an industrially advantageous method for producing an alkylfluorenone useful as an intermediate for various organic products. SOLUTION: This method for producing a hydrocarbon group-substituted fluorenone is to oxidize a fluorene having at least one hydrocarbon group on an aromatic ring with molecular oxygen in the presence of a caustic alkali and a phase transfer catalyst.
