4,4'-Vinylidenebis(N,N-dimethylaniline)(CAS: 7478-69-5)

4,4'-Vinylidenebis(N,N-dimethylaniline) is a white crystalline solid with a molecular weight of approximately 262.3 g/mol. It has a low solubility in water but is soluble in organic solvents such as benzene and toluene. This compound is known for its poor reactivity under normal conditions but can undergo polymerization under certain initiating conditions.

4,4'-Vinylidenebis(N,N-dimethylaniline) is typically synthesized via the coupling reaction of 4-(dimethylanilino)benzaldehyde with itself under basic conditions. Commonly, this involves the use of a strong base like sodium hydride or potassium tert-butoxide with a yield of about 80-85%. The reaction is exothermic and requires careful temperature control.

4,4'-Vinylidenebis(N,N-dimethylaniline) is primarily used in the pharmaceutical industry for the synthesis of certain drugs. It is also utilized in the polymer industry for the development of functional polymers. Additionally, it has potential applications in the semiconductor industry as a precursor for organic semiconductors.

When handling 4,4'-Vinylidenebis(N,N-dimethylaniline), it is essential to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up immediately using appropriate absorbents, and the area should be thoroughly washed down with water. An SDS (Safety Data Sheet) should always be readily available for reference in case of emergencies.
