Dear Syadza,

Vinyl bromide is a highly reactive compound that can be used in a variety of chemical reactions. It is typically used as a reagent to synthesize other chemicals, such as polymers, and is often used in the presence of a solvent, such as THF (tetrahydrofuran).

If you are using a 1 M solution of vinyl bromide in THF as the reagent in your reaction, you will need to carefully control the reaction conditions to ensure that the reaction proceeds smoothly. Depending on the specific reaction that you are performing, you may need to use a specific temperature, pH, or solvent concentration to achieve the desired outcome.

In general, it is recommended to perform reactions involving vinyl bromide at low temperatures, as the compound is highly reactive and can decompose or polymerize rapidly at higher temperatures. Therefore, you may need to use a temperature below -30°C, or use a cooled solvent or reaction vessel to keep the temperature of the reaction low.

It is also important to carefully control the concentration of vinyl bromide in the reaction mixture, as well as the ratio of vinyl bromide to any other reactants. It is generally recommended to use a relatively low concentration of vinyl bromide in the reaction mixture to minimize the risk of unwanted side reactions or decomposition.

It is always important to carefully read the literature and follow the recommended reaction conditions when using vinyl bromide or any other reactive chemical. It is also a good idea to consult a chemistry expert or follow established protocols to ensure the safety and success of the reaction.

I hope this was helpful.

Yours sincerely,

Dear Edgar Manuel Cambaza

Thank you so much for your explanation. I think the problem of my reaction is that I poured the vinyl bromide solution instantly. Maybe I have to add it dropwise. Thank you so much.
