Buta-1 3-diene reacts with excess bromine

WebThe 1,4-dibromide is only formed when the reaction is heated and is the thermodynamic product. The mechanism is the electrophilic attack on the diene to give a bromonium ion, which bromide opens to give the dibromide. 1,2-dibromide can then react further because it can undergo nucleophilic substitution. Bromide is a good nucleophile and leaving ... WebMar 12, 2024 · However, the mechanism for this reaction is not given. Also, the formation of a dicarboxylic acid on the parent ring is not explained.
