What is the synthesis method of 2,7-diiodine-9,9-dimethyl-9H-fluorene?

The synthesis method of 2% 2C7-dinaphthalene-9% 2C9-dimethyl-9H-fluorene is based on the ancient method of "Tiangong Kaiwu", which is roughly as follows:
First, all kinds of materials need to be prepared to find naphthalene with good texture, and an appropriate amount of methylating reagents, such as iodomethane, and suitable catalysts, such as anhydrous aluminum trichloride.
In a clean reactor, first place the naphthalene in it. The kettle needs to be dry and airtight. Slowly inject an appropriate amount of organic solvent, such as dichloromethane, to fully dissolve the naphthalene into a uniform solution. The color of the solution should be clear without impurities.
Then, at a low temperature and stirring state, slowly add anhydrous aluminum trichloride. At this time, the stirring cannot be stopped, so that the catalyst is evenly dispersed in the solution. When the catalyst is miscible with the naphthalene solution, add iodomethane dropwise. When adding iodomethane, you need to be especially cautious, because the reaction is more violent to prevent accidents.
During the reaction, you need to pay close attention to the change of temperature, and use an ice-water bath or other temperature control methods to keep the reaction temperature constant in a suitable range, about 0 to 10 degrees Celsius. The reaction takes a long time, or it takes several hours or even longer, and the reaction is continuously stirred during this time to fully contact the reactants to promote the completion of the reaction.
When the reaction is asymptotically terminated, test the degree of reaction by thin-layer chromatography or other suitable analytical means. If the reaction is complete, pour the reaction mixture into a container containing ice water to quench the reaction. At this time, a white precipitate can be seen, which contains the target product 2% 2C7-dinaphthalene-9% 2C9-dimethyl-9H-fluorene.
Collect the precipitate by filtration and rinse it several times with an appropriate amount of distilled water to remove impurities. After recrystallization with ethanol or other suitable organic solvent, pure 2% 2C7-dinaphthalene-9% 2C9-dimethyl-9H-fluorene crystals can be obtained. The crystal color is as white as snow, and it shines under light.
