introduction | 9, 9-dimethylfluorene-2-boric acid is white or light yellow solid powder at normal temperature and pressure, which is soluble in hot ethanol, but has poor solubility in water. It can be used as an intermediate in organic synthesis and medicinal chemistry. |
Use | 9, 9-dimethylfluorene-2-boric acid is used as an intermediate in organic synthesis and medicinal chemistry and material chemistry. The most conversion processes are carried out around boric acid on the benzene ring. Boric acid can be easily converted into various boric acid esters, etc. In addition, boric acid can participate in the classic Suzuki coupling reaction to construct carbon-carbon bonds, chan-lam the coupling reaction to construct carbon-oxygen bonds or carbon-nitrogen bonds, etc. Interestingly, with the help of the structure of biphenyl in 9,9-dimethylfluorene-2-boronic acid, by introducing this unit, the modification of the luminescent material molecules and the adjustment of the luminescent properties of the fluorescent molecules can be effectively achieved. |
Synthesis method | For the synthesis of 9, 9-dimethylfluorene-2-boric acid, the conventional synthesis method is to use 9, 9-dimethyl-2-bromofluorene as the starting material, and remove the bromine with a strong base such as n-butyl lithium to obtain the corresponding phenyl lithium reagent, then add the corresponding trimethyl borate or triisopropyl borate, and then add acid to promote the 1,2-migration of boron to obtain the product. In this process, the other two ester bonds will also undergo corresponding hydrolysis. So boric acid is obtained. |
environmental hazards | 9,9-dimethylfluorene -2-boric acid, as a boron-containing organic compound, is harmful to the water environment and cannot allow undiluted or large amounts of products to contact groundwater, waterways or sewage systems. |
