What are the chemical properties of 1-Ethenyl-3-Fluorobenzene?

1-Vinyl-3-fluorobenzene, an organic compound. Its molecular structure contains a fluorine atom and a vinyl group attached to a styrene ring. The chemical properties of this compound are unique and closely related to the properties of the styrene ring, fluorine atom and vinyl group.
First of all, the styrene ring is aromatic, the electron cloud is uniformly distributed, stable and can participate in electrophilic substitution reactions. In the case of electrophilic reagents, the styrene ring can provide electron pairs to form a sigma complex, which is then rearranged to lose protons and form substitution products. In 1-vinyl-3-fluorobenzene, the electron cloud of the styrene ring is changed by the influence of fluorine atoms and vinyl groups, resulting in slightly different reactivity from that of benzene.
Fluorine atoms have strong electronegativity, and the electron-withdrawing induction effect is significant. This effect reduces the electron cloud density of the benzene ring, weakens the activity of electrophilic substitution reaction, and affects the ortho and para-site localization effects. Usually, electrophilic reagents are more likely to attack the meta-site, because fluorine atoms absorb electrons, so that the density of the meta-site electron cloud is relatively high.
Vinyl contains carbon-carbon double bonds, which are unsaturated and can undergo addition reactions. It is common to react with bromine water or carbon tetrachloride solution of bromine, and the double bond is opened, and the bromine atom is added to the double-bond carbon to form a dibromo substitute. Under the action of the catalyst, it can also be added with hydrogen, hydrogen halide, etc. And the vinyl can undergo polymerization reaction, and the double bond is opened to
In addition, in 1-vinyl-3-fluorobenzene, there is a conjugation effect between the styrene ring and the vinyl group, which affects the distribution and stability of the molecular electron cloud, and then affects its chemical properties. The conjugation system reduces the molecular energy, enhances the stability, and changes the reactivity and selectivity at the same time.
In short, the properties and interactions of 1-vinyl-3-fluorobenzene-phenyl ring, fluorine atom and vinyl group show a variety of chemical properties and have important application value in organic synthesis and other fields.

This appearance feature is particularly critical when initially identifying and observing its state.
times and boiling points are about a certain temperature range, and the specific value will vary slightly due to experimental conditions, but roughly within this range. The characteristics of boiling point play a decisive role in the separation and purification of the compound. To obtain pure 1-vinyl-3-fluorobenzene from the mixed system, it can be achieved by distillation and other means according to its boiling point.
In addition, the melting point is also a specific value. Determination of the melting point helps to distinguish the purity of the compound. If there are few impurities, the melting point should approach the theoretical value; if there are more impurities, the melting point will shift, or decrease, or the melting range will become wider.
In terms of density, it has its specific value. This density characteristic is of great significance when it comes to liquid-liquid separation, mixing, etc. By knowing its density, it can be judged that it floats or sinks in the mixed liquid, and it can assist in the design of the separation scheme.
The solubility cannot be ignored. In organic solvents, such as common ethanol and ether, it often has a certain solubility and can dissolve with it to form a uniform solution. However, in water, the solubility is poor and it is difficult to miscible with water. This difference in solubility is an important consideration in the process of extraction and the construction of the reaction system.
In addition, 1-vinyl-3-fluorobenzene has a certain volatility and will slowly evaporate in the air. Its vapor pressure varies at different temperatures, which affects its behavior in the gas phase.

What are the preparation methods of 1-Ethenyl-3-Fluorobenzene?

The preparation method of 1-vinyl-3-fluorobenzene is now described by you.
One method can be started from 3-fluorobenzaldehyde. Shilling 3-fluorobenzaldehyde reacts with Phospho-Yellide reagent through Wittig, which is a common method for forming carbon-carbon double bonds in organic synthesis. The carbonyl group of the aldehyde group in 3-fluorobenzaldehyde interacts with Phospho-Yellide reagent, and the carbonyl oxygen binds to Phospho-Yellide phosphorus, and then a elimination reaction occurs to form a carbon-carbon double bond, resulting in 1-vinyl-3-fluorobenzene. The reaction conditions are relatively mild, but the preparation of phosphine Yelid reagent may be a little more complicated. It is necessary to first react halogenated hydrocarbons with triphenylphosphine to obtain quaternary phosphonium salts, and then treat quaternary phosphonium salts with strong bases to obtain phosphine Yelid reagent.
The second method can use 3-fluorobrobenzene as raw material. First, 3-fluorobrobenzene is reacted with magnesium chips in anhydrous ether or tetrahydrofuran to prepare Grignard's reagent 3-fluorophenyl magnesium bromide. Grignard's reagent has strong nucleophilicity, and then reacts with ethynyl halides (such as ethynyl bromide) to introduce vinyl, and then 1-vinyl-3-fluorobenzene However, this process requires strict anhydrous and oxygen-free conditions. Due to the easy decomposition of Grignard's reagent in contact with water or oxygen, the experimental operation requirements are quite high.
Another method can be started from 3-fluoroaniline. The 3-fluoroaniline is first reacted by diazotization, and the 3-fluoroaniline is treated with sodium nitrite and hydrochloric acid at low temperature to form a diazonium salt. The diazonium salt is unstable, and then the diazonium salt and vinyl borate are coupled under the action of a suitable catalyst (such as palladium catalyst), and 1-vinyl-3-fluorobenzene can also be obtained. This method relies on high-efficiency catalysts, and the diazotization reaction requires precise control of temperature to prevent the decomposition of diazonium salts from
