What are the chemical properties of 2-Tetrafluoroethoxynitrobenzene?
2-Tetrafluoroethoxy-nitrobenzene is one of the organic compounds. Its unique chemical properties are quite important to chemists.
In this compound, the nitro group (-NO ³) is connected to the tetrafluoroethoxy group (-OCH ³ CF
) on the benzene ring. The nitro group has strong electron-absorbing properties, which can reduce the electron cloud density of the benzene ring, weaken the electrophilic substitution reaction activity of the benzene ring, and reduce the density of the adjacent and para-position electron clouds even more, so the electrophilic reagent mostly attacks the intermediate position.
In the tetrafluoroethoxy group, the fluorine atom is extremely electronegative, so that the group also has an electron-absorbing effect. However, it is connected to the benzene ring, and under certain conditions, it may affect the spatial structure and electron distribution of the molecule. This structural feature makes 2-tetrafluoroethoxy nitrobenzene exhibit special activity in chemical reactions.
In the field of organic synthesis, because of its electron-absorbing group, it can be used as a substrate for nucleophilic substitution reactions. Nucleophilic reagents can attack the relatively high electron cloud density on the benzene ring, causing substitution reactions to occur, and then constructing new organic compounds. And the fluorine atom of the compound endows it with special physical and chemical properties, such as high stability, low surface energy, etc., or has potential applications in the fields of materials science. It may have certain solubility in organic solvents, which can help it participate in various homogeneous reactions. However, the specific solubility depends on the type of organic solvent and the interaction between molecules.
What is 2-Tetrafluoroethoxynitrobenzene production method?
The preparation method of 2-tetrafluoroethoxy-nitrobenzene is not detailed in the ancient book "Tiangong Kaiwu", but it can be deduced by traditional chemical process ideas.
First, nitrobenzene is used as the starting material. Nitrobenzene can be prepared by nitrification of benzene, benzene is co-heated with concentrated nitric acid and concentrated sulfuric acid, and hydrogen on the benzene ring is replaced by nitro to obtain nitrobenzene.
To obtain 2-tetrafluoroethoxy-nitrobenzene, nitrobenzene needs to be reacted with a reagent containing tetrafluoroethoxy. TFE can be prepared first, and tetrafluoroethanol can be added with TFE and water under an appropriate catalyst to obtain tetrafluoroethanol. TFE reacts with a base to form alkoxides, such as reacting with sodium hydroxide to
At the same time, the nitrobenzene is halogenated, and under specific conditions, the halogen atom is introduced at a specific position on the nitrobenzene ring. For example, under the action of a catalyst, the halogen is introduced at the ortho or para-position (taking the ortho position as an example) to obtain o-halonitrobenzene.
Subsequently, the o-halonitrobenzene undergoes a nucleophilic substitution reaction with sodium tetrafluoroethoxyethanol, and the tetrafluoroethoxy group replaces the halogen atom to obtain 2-tetrafluoroethoxy nitrobenzene.
Second, there are other methods. Using phenol as the starting material, nitrophenol is first nitrified to obtain nitrophenol, and the nitro group can locate the hydroxyl o-para-position. After reaction with tetrafluorohaloethane under alkaline conditions, tetrafluoroethoxy substituted phenolic hydroxyl hydrogen to obtain the target product 2-tetrafluoroethoxy nitrobenzene. During the reaction, the solvent, temperature, catalyst and other conditions need to be precisely controlled to improve the yield and purity.
