Some common heterocyclic compound, 1173707-01-1, name is N-(5-Fluoro-2-iodophenyl)acetamide, molecular formula is C8H7FINO, 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. COA of Formula: C8H7FINO

General procedure: N-(2-iodophenyl)acetamide (100.0 mg, 0.38 mmol, 1.0 equiv) in CH3CN (5.0 mL) was added sequentially with PdCl2(PPh3)2 (5.4 mg, 0.01 mmol, 0.02 equiv), Ph3P (4.0 mg, 0.02 mmol, 0.04equiv), 1-chloro-4-ethynylbenzene (57.6 mg, 0.42 mmol, 1.1 equiv). The resulting solution was degassed by passing through a steady stream of argon for 30 min (flask 1). In the meantime in another flask, a mixture of CuI (3.0 mg, 0.02 mmol, 0.04 equiv) in Et3N was also degassed bypassing through a steady stream of argon for 30 min (flask 2). After degassing, the mixture ofCuI in Et3N in flask 2 was transferred into the solution in flask 1 using a syringe with wide-boarneedle which resulted in the reaction solution turning yellow and giving white precipitates. The reaction mixture was allowed to stir at room temperature overnight and was quenched byaddition with sat. aq. NH4Cl. The separated aqueous phase was extracted with EtOAc (3x times).The combined organic phases were washed with sat. aq. NaCl, dried over anh. Na2SO4 and concentrated under reduced pressure. The crude material was purified by SiO2 column chromatography eluting with 30-50% EtOAc-hexane to yield 114.6 mg of compound 1d (>99%)as a white solid.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1173707-01-1, its application will become more common.

Application of 5876-51-7, 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. 5876-51-7 name is 5-Iodobenzo[d][1,3]dioxole, 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.

General procedure: All reactions were carried out in an 80 mL Teflon-lined stainless steel reactor equipped with a magnetic stirring bar. Typically, in a glovebox, the aryl iodides (1.0 mmol), RhI3(0.025 mmol), PPh3 (0.1 mmol), Et3N (1.2 mmol), and DMA (2 mL) were loaded into the reactor. Then, the autoclave was screwed up, charged with CO and H2 to a total pressure of 10 bar (1:1) and transferred to an oil bath preheated at 90 C, which was controlled by a Haake-D3 temperature controller. After completion of the reaction, the reactor was cooled in iced water and the gas carefully vented. The conversion and yield of the aryl iodides and arylaldehydes were determined by GC analysis using dodecane as an internal standard. For yield determination of the other products, the reaction mixture was first analyzed by GC-MS to determine the structures of the aromatic aldehyde products. Then, CH2Cl2 (5 mL) was added to the reaction mixture, after which deionized water (10 mL) was added to extract the solvent DMA for 5 times. The organic layer was dried over anhydrous Na2SO4, concentrated by rotary evaporation and finally purified by column chromatography on silica gel using n-hexane/ethyl acetate as eluent to obtain the pure products and isolated yields.
