| titleOfInvention | Production of 9,9-dialkylfluorene |
| abstract | PURPOSE: To provide easily, safely and at a low cost in high yield the title compound useful as an intermediate for dyes, medicines, monomers to produce polymers. n CONSTITUTION: The objective 9,9-dialkylfluorene can be obtained by reaction at normally -20 to 100°C (pref. 0-40°C) between (A) fluorene and (B) normally ≥2 molar times (pref. 2.5-4 molar times), based on the raw material A, of an alkyl chloride in a polar aprotic solvent such as dimethylsulfoxide, dimethylformamide or N,N-dimethylimidazolidine in the presence of 2-5 (pref. 2.5-3.5) molar times, based on the raw material, of a sodium alkoxide. n COPYRIGHT: (C)1992,JPO&Japio |
