alpha,alpha-Dibromotoluene Benzal bromide ALDRICH
?,?-Dibromotoluene undergoes polymerization with excess Mg to give poly(phenylmethylene)s. It reacts with NaSO2Me at 110C to yield a mixture of the monosulfone and ?,?-disulfone. It undergoes copolycondensation with ?,??-dibromo-p-xylylene in the presence of excess Mg via nucleophilic substitution of in situ generated Grignard reagents.
