Reference of 10485-09-3, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 10485-09-3, name is 2-Bromoindene, This compound has unique chemical properties. The synthetic route is as follows.
To a solution of 9.49 g (48.7 mmol) of 2-bromo-lH-indene in 490 ml of ether, 12.3 g (46.3 mmol) of Zr(NMe2)4 was added. The reaction mixture was stirred for 12 h and then evaporated to dryness. The residue was dissolved in 500 ml of toluene, and 23.1 g (151 mmol) of bromotrimethylsilane was added. The mixture was stirred for 24 h at room temperature, evaporated to a volume equal to ca. 250 ml, and filtered through a glass frit (G4). Crystals that precipitated at a temperature of 3O0C from the filtrate were separated, washed with 3 x 20 ml of cold dichloromethane, and dried in vacuum. Yield 16.1 g (66%) of yellow crystalline product.Anal. calc. for C9H6Br4Zr: C, 20.59; H, 1.15. Found: C, 20.68; H, 1.20.1H NMR (CDCl3): delta 7.75 (dd, 2H, J = 6.5 Hz, J = 3.0 Hz, 5,6-H), 7.43 (dd, J = 6.5 Hz, J = 3.0 Hz, 2H, 4,7-H), 7.13 (s, 2H, 1,3-H).
The chemical industry reduces the impact on the environment during synthesis 2-Bromoindene. I believe this compound will play a more active role in future production and life.
