Fluorene is one of the separation products of coal tar. It has a large output, a wide range of uses, and a low price. Its derivatives are used as important fine chemicals in the fields of medicine, pesticides, dyes, plastics and functional polymer materials [1]. Fluorenone is one of fluorene derivatives, as an important fine chemical intermediate, it is widely used in organic synthesis. The research of fluorenone is of great significance in improving the added value of fluorene.
