Related Products of 33348-34-4, 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. 33348-34-4, name is 4-Amino-3-iodobenzonitrile, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: In a flame-dried flask, AlMe3 (2 M in toluene, 1.11 mL, 2.18mmol, 1.2 equiv) was added to dry toluene (3.0 mL) under anitrogen atmosphere. The mixture was cooled to 0 C, and the2-iodoaniline (2.0 mmol, 1.1 equiv) in dry toluene (4.0 mL) was added. The mixture was stirred for a further 5 min at 0 C. Theice bath was removed, and the mixture was stirred for 20 min atroom temperature. The mixture was cooled to 0 C again, and cyclopentene carboxylate 2b (1.82 mmol, 1.0 equiv) in drytoluene (3.0 mL) was added dropwise over 2 min to the mixture. After stirring for 10 min at 0 C, the mixture was heated to 60 C, and stirring was continued for 16 h. After cooling to room temperature, HCl (1 M, 8.0 mL) was added. (Caution: gas evolution,exotherm.) The mixture was stirred for 15 min, then water (20 mL) and EtOAc (30 mL) were added. The mixture was extracted, the organic phase was separated, and the aqueous phase was re-extracted one more time with EtOAc (30 mL). Thecombined organic phases were washed with brine and dried (MgSO4). After filtration, the solvent was removed under reduced pressure, and the crude mixture was purified by column chromatography.
The chemical industry reduces the impact on the environment during synthesis 4-Amino-3-iodobenzonitrile. I believe this compound will play a more active role in future production and life.
