α,α-Dibromotoluene undergoes polymerization with excess Mg to give poly(phenylmethylene)s. It reacts with NaSO2Me at 110°C to yield a mixture of the monosulfone and α,α-disulfone. It undergoes copolycondensation with α,α′-dibromo-p-xylylene in the presence of excess Mg via nucleophilic substitution of in situ generated Grignard reagents.
D 2808 (OTTO) α,α-Dibromotoluene, 97% Cas 618-31-5 - used to treat wastewater by removing metals, such as iron and copper, that are not removed by conventional methods.
