The invention relates to a one-pot method for preparing 2-bromo-9,9-diphenylfluorene and belongs to the technical field of organic synthesis. The method comprises steps shown in the specification. The reaction can be finished in one reactor, particularly for a chlorination reaction, intermediate products are not required to be separated out, a subsequent reaction of replacement of chlorine atoms with benzene rings is performed after a system reactant and a catalyst are directly added, the whole operation is simple, and the technology is reliable and suitable for enlargement; besides, by means of the used catalyst, side reactions can be effectively reduced, the product yield is increased to be higher than 90%, meanwhile, separation can be realized through filtration after the reaction due to the fact that the catalyst is a solid catalyst, and the after-treatment process is simplified.
