Synthesis of Fluorenebisphenoxy Derivatives by Acid-sulfur Compound Catalyzed Condensation Reaction
An efficient method for the synthesis of fluorenebisphenoxy derivatives from fluorenone and phenoxy compounds is successfully performed by the combined use of concentrated sulfuric acid as catalyst and 3-mercaptopropionic acid as co-catalyst. Several fluorenebisphenoxy derivatives are obtained in good yields by this one-step reaction.
