What is the Chinese name of Benzene, 1,2 - diiodo -?
The author of "Tiangong Kaiwu" was written by Song Yingxing in the Ming Dynasty. It contains all kinds of processes and technologies in detail, and occupies an important position in the history of science and technology in China. However, the chemical knowledge and naming rules at that time were very different from those of today. The so-called "Benzene, 1,2 - diiodo-" in the classical style of "Tiangong Kaiwu" today, it may be difficult to find an accurate correspondence.
If it is given the name, it can be called "ortho-isomer of diiodobenzene". Benzene, the cyclic hydrocarbon of today's chemistry, although it did not have this precise understanding in the past, its structure is cyclic, or it can be associated with "genus of cyclic hydrocarbons". " 1, 2 - diiodo- ", indicating that the position of the iodine atom on the benzene ring is adjacent, that is, the position of the ortho," diiodine generation ", indicating that the diiodine atom replaces the hydrogen atom on the benzene ring. Therefore, in the style of ancient classical Chinese, this substance can be called" the cyclic hydrocarbon of the ortho-diiodine generation ". Although it is not directly related to the original content of" Tiangong Kaiwu ", it is named in this way according to the cognition and expression habits of that time, and it can represent its approximate structure and characteristics.

What are the synthesis methods of Benzene, 1, 2 - diiodo -
To make 1,2-diiodobenzene, you can follow the following ancient method:
Take the benzene first, mix it with nitrate and sulfur. The temperature is about fifty to sixty degrees, and the nitrobenzene is obtained by nitrification. This step is because the π electrons of benzene are rich in electrons and are vulnerable to electrophilic attack. Nitro positive ions are strong electrophilics, so they can be electrophilically substituted with benzene to obtain nitrobenzene.
The nitrobenzene is returned with iron and hydrochloric acid to obtain aniline. This is because iron and hydrochloric acid can provide active hydrogen to convert nitro groups into amino groups, which is a common method of nitro reduction. After
, aniline interacts with iodomethane, through nucleophilic substitution, the lone pair electrons on nitrogen attack the carbon of iodomethane, and the iodine ions leave to obtain N-methylaniline.
Then make N-methylaniline co-warm with iodine and an appropriate amount of oxidant (such as hydrogen peroxide). Iodine increases in activity under the action of oxidant, and is prone to electrophilic substitution with benzene ring, and due to the positioning effect of amino groups, it mainly reacts in adjacent and para-sites. 1,2-diiodine-N-methylaniline can be obtained through regulation.
Finally, 1,2-diiodobenzene is obtained by treating 1,2-diiodobenzene with appropriate reagents (such as sodium nitrite and hydrochloric acid) to form diazonium salts, followed by hydrolysis or other denitrification methods to remove nitrogen. In this series of steps, by taking advantage of the reaction characteristics of each step, iodine atoms are gradually introduced and benzene rings are modified to achieve the purpose of preparing 1,2-diiodobenzene.
