The addition of HBr to buta-1,3-diene results in1,2-addition at cold temperatures and 1,4-addition atwarm temperatures. If the 1,2-adduct is first formed atcold temperatures and then warmed up, the 1,4-adductis formed, as shown here. Draw a mechanism for thisHHНeatBrBr1,2-Adduct1,4-Adductisomerization.
