Electric Literature of 755027-21-5, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 755027-21-5 name is 4-Chloro-1-iodo-2-methoxybenzene, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

A dry round bottomed flask was charged with KOTBU (1.903 g, 17.0 mmol), 5-chloro- 2-iodoanisole (4.054 g, 15.1 mmol), Pd2dba3 (144 mg, 0.16 mmol), DPEPhos (176 mg, 0.33 mmol) and 3-FLUORO-THIOPHENOL (1.903 g, 17.0 mmol). The flask was evacuated and BACKFILLED with Ar three times. Dry toluene (80 mL) was added and the mixture stirred at 95 C for 2 h. The mixture was filtered through a pad of silica gel followed by adsorption onto silica gel. After purification by flash chromatography using silica gel, eluting with heptanes/EtOAc, 97: 3, the title compound was obtained as a yellow oil (3.41 g, 85%).

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-Chloro-1-iodo-2-methoxybenzene, and friends who are interested can also refer to it.

Reference of 755027-21-5, The chemical industry reduces the impact on the environment during synthesis 755027-21-5, name is 4-Chloro-1-iodo-2-methoxybenzene, I believe this compound will play a more active role in future production and life.

A mixture of Example 56A (67mg, 0.2 MMOL), Example 59B (37mg, 0.2 mmol), CYMAP ligand (11. 8mg, 0.03 mmol), Pd (OAc) 2 (4.9mg, 0.002 mmol), and CsF (91MG, 0.6 mmol) in DME (8 mL) and methanol (4 mL) was heated to reflux overnight, cooled to room temperature, and partitioned between water and ethyl acetate. The aqueous layer was extracted with ethyl acetate and the combined organic layers were washed with brine, dried (MGS04), filtered, and concentrated under vacuum. The residue was purified by flash column chromatography on silica gel with 1: 1 HEXANES/ETHYL acetate to provide 0.036g (50%) of the desired product. MS (ESI) m/e 359 (M+H) + ; 1H NMR (300 MHz, DMSO-d6) 8 9.88 (s, 1H), 7.99 (s, 1H), 7.79 (d, J = 8.14 Hz, 1H), 7.70 (d, J = 8.14 Hz, 1H), 7.27-7. 36 (m, 3H), 6.91-7. 01 (m, 5H), 4.00 (s, 3H), 2.56 (s, 3H).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Chloro-1-iodo-2-methoxybenzene, other downstream synthetic routes, hurry up and to see.

These common heterocyclic compound, 755027-21-5, name is 4-Chloro-1-iodo-2-methoxybenzene, 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. Product Details of 755027-21-5

Example 60A 4-CHLORO-2-METHOXYBENZONITRILE A mixture of Example 59A (2.68g, 10 mmol), Zn (CN) 2 (0.654g, 5.5 mmol), and Pd (PPh3) 4 (0. 577G, 0.5 mmol) in DMF (15 mL) was stirred at 90 C for 6 hours and cooled to room temperature. The reaction mixture was poured into water (500 ML) and extracted with ethyl acetate several times. The combined extracts were washed with water and brine, dried (MGS04), filtered, and concentrated under vacuum. The residue was purified by flash column chromatography on silica gel with 9: 1 hexanes/ethyl acetate to provide 1.34g (90%) of the desired product. MS (DCI) m/e 168 (M+H) ; H NMR (300 MHz, CDC13) 8 7.49 (d, J = 8.1 Hz, 1H), 6.97-7. 03 (m, 2H).

The synthetic route of 4-Chloro-1-iodo-2-methoxybenzene has been constantly updated, and we look forward to future research findings.
