Heptakis(6-Bromo-6-Deoxy)-灏?Cyclodextrin (cas: 53784-83-1) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Synthetic Route of C42H63Br7O28

Synthesis of heptakis(2-O-methyl)-灏?cyclodextrin was written by Takeo, Kenichi;Kuge, Takashi. And the article was included in Staerke in 1976.Synthetic Route of C42H63Br7O28 This article mentions the following:

The title compound, I (R = OH, R1 = Me) (II), was prepared in 80% yield by methylation of I (R = Br, R1 = H) with Me2SO4-BaO-Ba(OH)2 in DMF at room temperature for 40 hr, followed by treatment with NaOBz in (Me2N)3PO at 90鎺?and deesterification with NaOMe in MeOH. NMR comparison of II and the tetradeca-O-methyl ether (III) of 灏?dextrin confirmed that the Me groups in III are located at O-2 and O-6. In the experiment, the researchers used many compounds, for example, Heptakis(6-Bromo-6-Deoxy)-灏?Cyclodextrin (cas: 53784-83-1Synthetic Route of C42H63Br7O28).
