What is the chemical structure of this product "Biphenyl, 4,4 '-diiodo"?

"The chemical structure of the product'Biphenyl, 4,4 '-diiodo' is composed of two benzene rings connected by a single bond, and an iodine atom is connected at the 4 and 4 'positions corresponding to the two benzene rings.
In this compound, the benzene ring has a planar ring structure composed of six carbon atoms, and the carbon atoms are alternately connected by conjugated double bonds to form a stable aromatic system. The two benzene rings are connected by a single bond, so that the whole molecule can rotate around this single bond to a certain extent, showing different spatial conformations. The iodine atoms connected at the 4 and 4' positions of the benzene ring have a significant impact on the electron cloud distribution and chemical properties of the molecule due to their high electronegativity. The introduction of iodine atoms increases the polarity of molecules, and at the same time, due to its large atomic radius, it occupies a certain position in space, which affects the interaction between molecules.
This chemical structure endows the compound with unique physical and chemical properties, and may have specific application value in organic synthesis, materials science and other fields. "

What are the preparation methods of "Biphenyl, 4,4 '-diiodo"?

The method of making 4,4 '-diiodobiphenyl has been around for a long time. One method is to first make biphenyl and iodine react in an appropriate solvent with a catalyst. Usually copper powder or its salts are used as catalysts, and the two are combined under heating. The structure of biphenyl is stable, but with the help of catalysis, iodine atomic energy replaces the hydrogen atom of biphenyl's 4,4' -position and gradually forms 4,4 '-diiodobiphenyl.
Another method can be used with organometallic reagents. Biphenyl-derived Grignard reagent or lithium reagent interact with the iodine source. Grignard's reagent is prepared with biphenyl and magnesium in anhydrous ether and other solvents, and then reacts with iodine. The magnesium-halide bond is active, which can lead iodine atoms into the 4,4 '-position of biphenyl, and then obtain 4,4' -diiodobiphenyl.
There are also those based on aromatic electrophilic substitution reaction. First, the biphenyl is activated to change the electron cloud density of the benzene ring, which is conducive to the attack of electrophilic reagents. Later, the electrophilic reagent of iodine, such as the active intermediate formed by iodine and a strong oxidizing agent, reacts with the activated biphenyl to introduce iodine atoms precisely at the 4,4 '-position to obtain the required 4,4' -diiodobiphenyl. Each of these methods has its own length, and it should be used according to the actual needs
