The addition of HBr to buta-1,3-diene results in 1,2-addition at cold temperatures and 1,4-addition at warm temperatures. If the 1,2-adduct is first formed at cold temperatures and then warmed up, the 1,4-adduct is formed, as shown here. Draw a mechanism for this H H Нeat Br Br 1,2-Adduct 1,4-Adduct isomerization.

Can someone explain to me the mechanism for the reaction? I don't know what type of reaction this is and how they add together to create the product. I do understand the actual product is correct because having all substituents equitorial is favorable.
