2-Vinylthiophene(CAS: 1918-82-7)

2-Vinylthiophene (CAS: 1918-82-7) is a colorless liquid with a density of approximately 0.94 g/cm³. Its molecular weight is 94.12 g/mol. It is slightly soluble in water but miscible with most organic solvents. It is highly reactive due to the presence of a vinyl group and a thiophene ring, making it susceptible to both electrophilic and nucleophilic substitution reactions.

2-Vinylthiophene (CAS: 1918-82-7) is typically synthesized via the Wittig reaction, where a vinyl phosphonium salt reacts with thiophene. This method provides good yields and selectivity. Another method involves the reaction of propargyl bromide with thiophene in the presence of a base to form the desired product.

2-Vinylthiophene (CAS: 1918-82-7) is primarily used in the synthesis of various polymers, particularly in the production of conductive polymers. It is also used in the pharmaceutical industry for the synthesis of certain drugs. Additionally, it has applications in sensors and semiconductors due to its electronic properties.

2-Vinylthiophene (CAS: 1918-82-7) should be handled with care due to its reactivity. It should be stored in a cool, dry place away from sources of ignition. Protective equipment such as gloves, goggles, and a lab coat is essential. Handling should be done in a well-ventilated area or a fume hood. In case of spills, ensure proper containment and disposal according to the SDS (Safety Data Sheet).
