Related Products of 108-37-2, A common heterocyclic compound, 108-37-2, name is 1-Bromo-3-chlorobenzene, molecular formula is C6H4BrCl, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A flask containing (l,5-cyclooctadiene)(methoxy)-iridium(I) dimer (84 mg, 0.13 mmol), 4,4′-di-tert butyl-2-2′-dipyridyl (69 mg, 0.26 mmol) and bis(pinacolato)diboron (1.29 g, 5.11 mmol) was purged with Ar, then hexanes (26 mL) and l-bromo-3- chlorobenzene (1 mL, 8.51 mmol) were added sequentially. The solution was stirred at RT for 18 h. The reaction mixture was concentrated in vacuo, re-dissolved in acetone (26 mL), then oxone (5.23 g, 8.51 mmol) in water (26 mL) added [Caution: exotherm observed]. After 10 min, the reaction mixture was diluted with DCM. The layers separated, and the aqueous layer extracted with DCM. The combined organics were washed with brine, dried and concentrated in vacuo to give the title compound (1.43 g, 81%). LCMS (Method 3): Rt 3.74 min, m/z 205, 207 [M-H+].
The synthetic route of 108-37-2 has been constantly updated, and we look forward to future research findings.
