7-Bromo-2-iodo-9, what is the synthesis method of 9-dimethyl-9h-fluorene

To prepare 7-bromo-2-iodine-9,9-dimethyl-9H-fluorene, the following method can be used.
Take 9,9-dimethyl-9H-fluorene as the starting material. This fluorene compound has a relatively stable structure because of the dimethyl attached to the 9-position carbon.
First, to introduce iodine atoms at the 2-position, an electrophilic substitution reaction can be used. In a suitable reaction system, such as glacial acetic acid as a solvent, an appropriate amount of iodine and an oxidizing agent such as hydrogen peroxide are added. Hydrogen peroxide can slowly release reactive oxygen species, prompting iodine elemental substance to generate electrophilic iodine cation (I 🥰). The electron cloud density at the 2 position on the fluorene ring is relatively high. The iodine cation attacks the 2 position carbon and undergoes electrophilic substitution to generate 2-iodine-9,9-dimethyl-9H-fluorene. This step requires controlling the reaction temperature and time. If the temperature is too high, it is easy to produce multi-iodine substitution by-products. If the time is too short, the reaction will be incomplete. Generally, the reaction can be reacted at 50-60 ° C for several hours, and the reaction progress can be monitored by thin-layer chromatography. The reaction can be stopped when the After that, pure 2-iodine-9,9-dimethyl-9H-fluorene was obtained by extraction, washing, drying, column chromatography and other steps.
Second, on the basis of the above products, bromine atoms were introduced at the 7th position. N-bromosuccinimide (NBS) can be selected as the bromine source, and a small amount of initiator such as benzoyl peroxide is added with carbon tetrachloride as the solvent. Under heating or light conditions, the initiator decomposes to produce free radicals, which prompts NBS to release bromine free radicals (Br ·). Bromine free radicals attack the 7 position of the fluorene ring, and a free radical substitution reaction occurs to generate the target product 7-bromo-2-iodine-9,9-dimethyl-9H-fluorene. This reaction process also requires close attention to the reaction conditions, the heating temperature should not be too high, and the light intensity and time should be precisely controlled to prevent excessive bromination. After the reaction is completed, a similar post-treatment operation is performed, including extraction to remove impurities, washing with sodium bicarbonate solution to remove acidic impurities, drying with anhydrous magnesium sulfate, and finally purification by column chromatography to obtain a high-purity 7-bromo-2-iodine-9,9-dimethyl-9H-fluorene product.

7-Bromo-2-iodo-9, what is the chemistry of 9-dimethyl-9h-fluorene?

7-Bromo-2-iodine-9,9-dimethyl-9H-fluorene is one of the organic compounds. Its chemical properties are interesting and unique.
In this compound, the introduction of bromine (Br) and iodine (I) atoms has a great impact on its properties. Both bromine and iodine are halogen elements with strong electronegativity. Therefore, 7-bromo-2-iodine-9,9-dimethyl-9H-fluorene exhibits a certain polarity. This polarity affects its solubility in different solvents. Generally speaking, compared with non-polar solvents, its solubility in polar solvents is better, because the polar molecules and polar solvents can form forces such as dipole-dipole interactions, which is conducive to dissolution.
Furthermore, the skeletal structure of fluorene endows this compound with certain rigidity and planarity. The substituents of 9,9-dimethyl have a steric hindrance effect on the molecule in space. This steric hindrance not only affects the spatial configuration of the molecule, but also has an effect on its chemical reactivity. For example, in some nucleophilic substitution reactions, steric hindrance may prevent the nucleophilic reagent from approaching the reaction check point, slowing down the reaction rate.
In terms of chemical reactivity, bromine and iodine atoms are both good leaving groups. Therefore, the compound can participate in many nucleophilic substitution reactions, such as reacting with nucleophiles containing nitrogen and oxygen to form new carbon-heteroatom bonds. In addition, due to the presence of halogen atoms, this compound may participate in metal-catalyzed coupling reactions, such as Suzuki coupling reaction and Stille coupling reaction. Such reactions are widely used in organic synthesis and can construct complex organic molecular structures.
From the perspective of electronic effects, the electron-absorbing induction effect of halogen atoms decreases the electron cloud density on the fluorene ring. The change of electron cloud density affects the reactivity of other check points on the fluorene ring, or changes the check point of electrophilic substitution reactions. At the same time, the electronic structure of the compound also affects its optical properties, such as under certain conditions, it may exhibit fluorescence properties, which may have potential applications in the field of optoelectronic materials.
