(1) Synthesis of 4-bromomethyl-5-methyl-1,3-dioxolen-2-one[the compound of formula (III) in which X is a bromine atom]: 3.42 g of 4,5-dimethyl-1,3-dioxolen-2-one (synthesised in accordance with Tetrahedron Letters, (1972), pages 1701-1704) was dissolved in 150 ml of carbon tetrachloride, and 5.34 g of N-bromosuccinimide and a catalytic amount of alpha,alpha’-azobisisobutyronitrile were added. The mixture was heated under reflux for 15 minutes. The reaction mixture was concentrated to half of its volume and the resulting insoluble matter was removed by filtration. Concentrating the filtrate gave a syrupy residue. The residue was distilled under reduced pressure to give a fraction boiling at 115¡ã to 120¡ã C./5 mm Hg which was 4.2 g (yield 73percent) of the captioned compound., 37830-90-3
