1-% pente-2,4,5-triene alkynes are alkynes, which have unique chemical properties and have the dual characteristics of alkenes and alkynes.
Looking at the addition reaction, due to the carbon-containing carbon double bond and carbon-carbon triple bond, both are electron-rich regions, which are easy to interact with electrophilic reagents. In case of hydrogen halide, it can be added according to the Markov rule. At the carbon-carbon double bond, the carbon with more hydrogen atoms is hydrogenated, and the halogen atom is added to the carbon with less hydrogen atoms; the carbon-carbon triple bond can also be added with it, or added in steps, to form a double-bond halide first, and when conditions are appropriate, it can be further added to a saturated halide. In case of bromine water, alkenyne can undergo electrophilic addition with it, causing bromine water to fade, and according to the reaction conditions and the proportion of reactants, the degree of addition can be controlled, or the double bond is added first, or both the double bond and the triple bond are added.
As far as oxidation is concerned, when treated with a strong oxidant such as acidic potassium permanganate, the carbon-carbon double bond and the triple bond will be oxidized and broken. At the double bond, according to its substitution, either carboxylic acid or carbon dioxide and corresponding carbonyl compounds will be formed; at the triple bond, carboxylic acid or carbon dioxide can be formed. If one end of the triple bond is alkynyl hydrogen, it can be oxidized to a carboxyl group.
The stability of this compound is slightly higher than that of partially solitary alkynes due to the delocalization of π electrons or a certain conjugation effect. The conjugation system affects the distribution of electron clouds, which in turn affects its chemical activity and reaction selectivity. In some reactions, the conjugation effect makes its reaction check point and reactivity different from ordinary alkynes.

To prepare 1-bromo-2,4,5-trifluorobenzene, the method is as follows:
First, 2,4,5-trifluorobenzene is used as the starting material, and it is obtained by diazotization and Sandmeier reaction. First, dissolve 2,4,5-trifluorobenzene into an appropriate amount of inorganic acid, usually hydrochloric acid or sulfuric acid, and cool it to a low temperature, generally 0-5 ℃. Then slowly add sodium nitrite solution dropwise, carry out diazotization reaction to generate 2,4,5-trifluorobenzene diazonium salt. This process requires strict temperature control to prevent the decomposition of diazonium salts. Then the diazonium salt solution is dropped into the hydrobromic acid solution containing cuprous bromide. After the Sandmeier reaction, the diazonium group is replaced by the bromine atom, and then 1-bromo-2,4,5-trifluorobenzene is obtained. After the reaction is completed, the product is extracted with an organic solvent, such as dichloromethane, ether, etc., and then purified by washing, drying, and distillation.
can also be prepared by reacting 2,4,5-trifluorophenylboronic acid with brominated reagents. Mix 2,4,5-trifluorophenylboronic acid with an appropriate amount of brominated reagents, such as N-bromosuccinimide (NBS) or bromine, in suitable solvents, such as dichloromethane and tetrahydrofuran, and add an appropriate amount of catalyst, such as copper salt or palladium salt. During the reaction, the temperature and reaction time need to be adjusted according to the selected reagent and catalyst. After the reaction is completed, regular separation methods, such as filtration, extraction, distillation, etc., can obtain pure 1-bromo-2,4,5-trifluorobenzene.
In addition, halogenated derivatives of 2,4,5-trifluorobenzene can also be achieved through halogen exchange reactions. Select suitable halogenated 2,4,5-trifluorobenzene derivatives, such as chloro or iodine, and react with brominating reagents under specific conditions.

The target product 1-bromo-2,4,5-trifluorobenzene can also be prepared by reacting with appropriate solvents and temperatures through separation and purification steps.

In the process of storage of 1-% -2,4,5-tribromobenzene, the following things should be paid attention to:
First, this is a chemical substance, with specific chemical properties. If it is not stored, it must be dried up, passed and lost. Due to moisture or its biochemical reactions, it will affect the product. In case of water vapor, or reactions such as hydrolysis, it should be changed.
Second, it should be stored separately. 1-% -2,4,5-tribromobenzene or oxidized benzene, even if it causes ignition, explosion and other hazards. If the oxidizing agent is placed in one layer, the oxidizing property of the oxidizing agent may promote some chemical reactions in 1-% -2,4,5-tribromobenzene to crack, releasing a lot of energy.
Third, it is necessary to follow the phase method in the final process. Hazardous chemicals that are not used are not used, and they should be equipped with safe application of phase, such as fire and so on. People also need to be trained, familiar with the dangerous characteristics and emergency treatment methods of 1-% 2,4,5-tribromobenzene. In the event of an accident such as leakage on the way, it can be quickly and properly treated to avoid damage.
Fourth, the storage container should be well sealed. To prevent 1-% 2,4,5-tribromobenzene from polluting the surrounding environment, and to prevent external objects from entering and affecting its safety. It is important to use a combined storage container, such as corrosion-resistant materials, because 1-% 2,4,5-tribromobenzene or some materials are corrosive.
Therefore, the storage of 1-%-2,4,5-tribromobenzene requires compliance with phase safety standards and caution in order to ensure that people's safety environments are not contaminated and to ensure the characterization of chemical substances in the entire process.
