2,5-Dibromobenzaldehyde (3) is synthesized by the oxidation of 2,5-dibromotoluene (1) via 2,5-dibromobenzylidene diacetate (2). Grignard reaction of hexylmagnesium bromide with 2 gives the normal addition product, 2,5-dibromo-α-hexylbenzyl alcohol (5) and reduced product, 2,5-dibromobenzyl alcohol (6).
