Dimethyl2,2'-Dibromoadipate Use and Manufacturing

Thionyl chloride (323 g, 2.71 mol) was added in 70 ml portions over 2 h to adipic acid (197 g, 1.35 mol) heated at 80 °C in a three-neck round bottom flask equipped with a reflux condenser and a constant pressure dropping funnel. The mixture was stirred until gas evolution ceased and partial solid adipic acid still remained. An additional 100 ml of thionyl chloride was added in 7 h, and heating was continued until gas evolution ceased. Bromine (473 g, 2.96 mol) was added dropwise to the pale yellow reaction mixture over an ice bath, and a white precipitate formed during the addition. The white precipitate was collected by filtration and recrystallized from MeOH to offer 253 g of 3 as white power with a yield of 53percent.
