Trans-2- (2-nitrovinyl) thiophene is one of the organic compounds. Its chemical properties are interesting and have unique reactivity.
In this compound, the thiophene ring is connected to the nitrovinyl group, giving it a special electron cloud distribution. The thiophene ring is an electron-rich system, while in the nitrovinyl group, the nitro group has strong electron-absorbing properties, causing the double-bond electron cloud to be biased towards the nitro group. This electronic effect greatly affects its chemical activity.
For the electrophilic substitution reaction, the electron cloud density on the thiophene ring is higher, which is more susceptible to the attack of electrophilic reagents. However, the electron-absorbing action of nitrovinyl decreases the density of the electron cloud at a specific location on the thiophene ring, thereby selectively changing the electrophilic substitution reaction region. For example, electrophilic reagents tend to attack places on the thiophene ring that are far away from the nitrovinyl group and where the electron cloud is relatively enriched.
In redox reactions, due to the presence of nitro groups, this compound can participate in the reaction as an electron receptor. Nitro groups can be reduced under appropriate conditions, and thiophene rings can also undergo oxidation reactions under the action of specific oxidants. In addition, its double-bonded parts can participate in addition reactions, such as Michael addition with nucleophiles, enriching its reaction path.
In the field of organic synthesis, trans-2- (2-nitrovinyl) thiophene is often used as a key intermediate due to its unique chemical properties. Through its various reactive activities, more complex organic molecular structures can be constructed, laying the foundation for the synthesis of new materials, drugs, etc.

The method of synthesizing trans-2- (2-nitrovinyl) thiophene has been discussed by many scholars throughout the ages. In the past, thiophene derivatives were often used as the starting material for synthesis. If a specific thiophene compound is selected, in a suitable reaction environment, it first meets the precursor material with nitrovinyl structure, and the two can be connected through a condensation reaction. This condensation reaction requires careful selection of catalysts. Common catalysts include alkali catalysts such as potassium carbonate and sodium hydroxide. Its function is to promote the reaction in the direction of generating the target product and increase the reaction rate.
Furthermore, the reaction temperature is also a key factor. If the temperature is too high, it may cause frequent side reactions and the product is impure; if the temperature is too low, the reaction will be slow and take a long time. Therefore, it is often controlled at a moderate temperature, such as an oil bath or a water bath to precisely adjust the temperature, generally between tens of degrees Celsius and 100 degrees Celsius, depending on the specific reaction.
In addition, the choice of reaction solvent cannot be ignored. Common organic solvents, such as dichloromethane, N, N-dimethylformamide, etc., can be used as reaction media. Different solvents have different effects on the solubility and reactivity of reactants, and must be carefully selected according to the reaction characteristics.
Recently, with the advance of science and technology, new synthesis paths have emerged. For example, the photocatalytic synthesis method, which uses a specific photocatalyst to excite the reaction under light conditions, provides a new path for the synthesis of trans-2- (2-nitrovinyl) thiophene. This method may have the advantages of mild reaction conditions and good selectivity compared with the traditional method, but it also requires high equipment and photocatalysts, and costs or considerations.

I have not obtained the exact price range of trans-2- (2-nitrovinyl) thiophene in the market. This compound may be used in scientific research and chemical fields, and its price often varies depending on purity, batch, supply and demand, and suppliers.
If the purity is high and the batch is small, the price may be high. For scientific research purposes, the purity requirements are strict, and the price is also high. If the batch is large, the unit price may drop due to economies of scale.
In chemical production, if the demand is strong and the supply is in short supply, the price will rise; if the market is saturated and the supply exceeds the demand, the price will be depressed.
For the exact price range, you can consult chemical raw material suppliers, chemical trading platforms, or professional chemical product quotation information. The price may range from a few dollars per gram to hundreds of dollars, but this is only speculation, and the truth depends on market dynamics.
