Abstract
Substituted-benzene-1,2-dicarbaldehydes were synthesized by the reaction of substituted-1,2-bis(dibromomethyl) benzenes with fuming sulfuric acid, followed by hydrolysis. The yields were significantly improved by introducing solid sodium bicarbonate into the reaction mixture before hydrolysis and workup.
