In the title compound, C13H13BrO4S, both C=C double bonds adopt an E conformation. The S atom has a distorted tetrahedral geometry with bond angles ranging from 102.17 (13) to 119.77 (14)°. The ethyl acrylate substituent adopts an extented conformation with all torsion angles close to 180°. In the crystal, molecules are linked into centrosymmetric R22(14) dimers via pairs of C—HO hydrogen bonds.

In the title compound, C13H12Cl2O4S, both C=C double bonds adopt an E conformation. The S atom has a distorted tetrahedral geometry with bond angles ranging from 103.03 (12) to 118.12 (13)°. The ethoxycarbonyl group is disordered over two sets of sites, with site-occupancy factors of 0.739 (11) and 0.261 (11). In the crystal, C—HO interactions link the molecules into chains molecules running parallel to the a axis.
