9-Fluorenone CAS:486-25-9
The carbonyl group in the 9-fluorenone molecule has typical properties of ketone compounds and can undergo addition reactions, reduction reactions, etc. For example, it can react with Grignard reagents to generate the corresponding alcohol, and can be reduced with a reducing agent to obtain 9-fluorenol. In addition, electrophilic substitution reactions can occur on the benzene ring of fluorenone. Due to the electron-withdrawing effect of the carbonyl group, the reaction mainly occurs at the meta position of the carbonyl group.
