General description
Crystal structure of 1,4-dibromo-2,5-dimethoxybenzene has been reported to be monoclinic and its asymmetric unit is composed of one-half of the molecule. Lithium diisopropylamide (LDA) mediated metallation of 1,4-dibromo-2,5-dimethoxybenzene has been proposed.
Application
1,4-Dibromo-2,5-dimethoxybenzene was used in the preparation of poly[(9,9-bis(6-(dibromohexyl)-2,7-fluorene))-alt-1,4-(2,5-dimethoxybenzene)], a water-soluble polyfluorene derivative.
