| titleOfInvention | Production of iodinated 9,9-dialkylfluorene |
| abstract | PURPOSE: To safely obtain a compound useful as an intermediate for dyes, medicines, monomers for polymers, etc., in high yield at a low cost using easy operation by reacting a 9,9-dialkylfluorene with iodine chloride. n CONSTITUTION: A 9,9-dialkylfluorene is reacted with iodine chloride in an inert solvent (e.g. acetic acid) under ordinary pressure to provide a mono- and a diiodine-substituted 9,9-dialkylfluorene. The mono- and diiodinated derivatives can selectively be obtained by regulating the amount of the iodine chloride added, reaction temperature and reaction time. When the monoiodinated derivative is obtained, the iodine chloride is used in a molar amount of 1.0-3 times based on the raw material to carry out the reaction at 30-80°C for 2-8hr. When the diiodinated derivative is obtained, the iodine chloride is used in a molar amount of 2.0-10 times based on the raw material to carry out the reaction at 60-90°C for 5-20hr. n COPYRIGHT: (C)1992,JPO&Japio |
