Some common heterocyclic compound, 31599-61-8, name is 4-Iodo-1,2-dimethylbenzene, molecular formula is C8H9I, 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. Formula: C8H9I
General procedure: A Schlenk tube with a magnetic stir bar was charged with Pd(OAc)2 (10 mol%, 0.0056 g), AgOTf (1.1 equiv., 0.0707 g), TBAB (20 mol%, 0.0161g), 2-phenylpyridine N-oxides 1 (0.25 mmol), iodobenzene and its derivatives 2 (0.375 mmol) and H2O (1 mL). The resulting solution was stirred at 100C for 12 h. The resulting organic layer was extracted with trichloromethane, treated with Na2SO4 and concentrated in vacuo. The product was isolated by short column chromatography using ethyl acetate and methanol as eluent.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 31599-61-8, its application will become more common.
