A cheap industrial method for making 1,2-dibromoindane represented by Formula (I), where the configuration of the bromine atoms on position 1 and position 2 can be trans or cis, or it can be a mixture of trans and cis isomers by reacting indene with hydrogen bromide in the presence of hydrogen peroxide. Water may be used as the solvent and another aprotic organic solvent may be present.
