The first reaction is the Bromination reaction in the Bromine molecule is created and which is substituted by the electrophilic aromatic substitution mechanism,
The second reaction is an example of the Diel's- alder reaction, with first the elimination of the sulphur dioxide and the [4+2] cycloaddition happens.
