Summary:Provided are: a method for producing a compound having a fluorene skeleton; a novel compound having a fluorene skeleton and having improved hue; and a method for producing the novel compound. The method for producing a compound having a fluorene skeleton is characterized in that: in a step in which a compound represented by formula (1) and a boric acid represented by formula (2) or (3) are reacted in a reaction solvent in the presence of a base and a palladium-based catalyst to obtain a compound having a fluorene skeleton represented by formula (4); at least dimethyl formamide is used as a reaction solvent; the novel compound having a fluorene skeleton, the hue of which is improved, is represented by formula (4) in which the Hazen unit chroma (APHA) of a 5 wt% solution obtained by dissolving in dimethylformamide is 50 or less. (In the formula, X1 and X2 each independently represent a halogen atom. ) (In the formula, each Z independently represents an optionally substituted aromatic group having 6-20 carbon at
