Sigma-Aldrich Benzal Bromide 97%

α,α-Dibromotoluene undergoes polymerization with excess mg to give poly(phenylmethylene)s[1]. It reacts with NaSO₂Me at 110°C to yield a mixture of the monosulfone and α,α-disulfone[2]. It undergoes copolycondensation with α,α′-dibromo-p-xylylene in the presence of excess mg via nucleophilic substitution of in situ generated Grignard reagents[3].
