Chlorine on Benzene Ring
If you want to make a compound of chlorine-benzene ring
, there must be a way. Now, the matter of chlorine-benzene ring is an important part of the transformation.
Chlorine, a halogen element, is active and can react with various things. Benzene ring, with specific structure, six-carbon ring, conjugated bond, stable and sexual.
When chlorine is in the benzene ring, there is an electrophilic method to replace it. Chlorine can replace the hydrogen of the benzene ring under the catalysis of an appropriate agent, such as iron trichloride. At the beginning of the reaction, chlorine and the catalytic agent combine to generate positive electricity. This chlorine is a kind of chlorine, which is rich in electricity of the benzene ring, and attacks its position on the ring. The hydrogen in the benzene ring is a leaving group, which is removed and combined with the residue in the agent, and finally obtains the production of chlorinated benzene ring.
This should also be done. It is necessary to control its temperature and observe the amount of its agent. If the temperature is high, it should be fast, and then it may produce by-products; if the agent is suitable, it should be smooth, and if the amount is inappropriate, it will hinder its formation. And if there is a other group on the benzene ring, it will also affect the temporary position of chlorine. It should be easy for the power supply group to make the benzene ring rich in electricity, and the chlorine is mostly in its adjacent and para-position; the electron-absorbing group makes the benzene ring lack of electricity, and it should be difficult, and the chlorine is mostly in its intermediate position.
