9-Chlorofluorene reacted with aromatic aldehydes and ketones in the presence of phase transfer catalyst, giving the Darzens condensation epoxy products.
Acyl chloride can efficiently be converted into anhydride under solid liquid phase transfer catalysis by using bis(triphenylphosphine)cobalt dichloride or bis(triphenylphospine)palladium dichloride as the catalyst.
