| titleOfInvention | Method for producing compound having fluorene skeleton and compound having fluorene skeleton containing few impurities |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a compound having a novel fluorene skeleton, which is excellent in optical properties, heat resistance, moldability and the like. A method for producing a compound having a fluorene skeleton represented by formula (1), comprising: (In the formula, ring Z is an (identical or different) aromatic group, R 1 and R 2 are each independently a hydrogen atom, a halogen atom, etc., Ar 1 and Ar 2 are substituents having 6 to 10 carbon atoms. An aromatic group which may be present, L 1 and L 2 are alkylene groups, j and k are each independently an integer of 0 or more, and m and n are each independently an integer of 0 to 5.) Formula (2) Pd/SiO 2 (2) and the content of the palladium element in the obtained compound having a fluorene skeleton satisfy the formula (3), and 0≦Pd≦10 ppm (3) A method for producing a compound having a fluorene skeleton, wherein the by-product represented by (4) is produced within a range of 3% or less. Ar 1 -Ar 1 , Ar 1 -Ar 2 or Ar 2 -Ar 2 (4) [Selection diagram] None |
