According to the procedure reported by Yu and co-workers [3], palladium acetate (22 mg, 0.10mmol), iodobenzene diacetate (644 mg, 2.0 mmol), iodine (507 mg, 2.0 mmol), and tetrabutylammonium iodine (739 mmol, 2.0 mmol) were added to a solution of 3-chlorobenzoic acid (313 mg, 2.0 mmol) in 1,2-dichloroethane (20 mL). The mixture was heated at 100 C with stirring for 2 h and then allowed to cool to room temperature. Iodobenzene diacetate (644 mg, 2.0 mmol) and iodine (507 mg, 2.0 mmol) were added to the mixture. After stirring at 100 C for 4 h, the resulting mixture was diluted with10% sodium carbonate. The aqueous layer was separated, washed with Et2O, and then acidified with 10% HCl. The resulting mixture was extracted with EtOAc and the organic layer was dried over Na2SO4; filtered; and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/EtOAc = 4/1) to give crude 5-chloro-2-iodobenzoic acid (223 mg) as a colorless solid, which was suspended in thionyl chloride (2 mL). After stirring under reflux conditions for 2 h, the resulting mixture was concentrated under reduced pressure. The remaining thionyl chloride was removed by azeotropic distillation with benzene. The residue was dissolved in anhydrous CH2Cl2 (3 mL). To the mixture were added isopropylamine (56 mg, 0.95 mmol) and triethylamine (240 mg,2.37 mmol) at 0 C under a nitrogen atmosphere. After stirring at room temperature for 13 h, the resulting solution was diluted with EtOAc. The mixture was washed with 10% HCl, saturated aqueous NaHCO3, water, and brine; dried overNa2SO4; filtered; and concentrated under reduced pressure. The residue was purified by recrystallization from hexaneand CHCl3 to give 19 (138 mg, 21% in 3 steps) as colorless needles.

Application of 31827-94-8, 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. 31827-94-8 name is 2-Bromo-1-(4-iodophenyl)ethanone, 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.

This was a 2-step reaction process. To a solution of (5)-5-(tert-butoxycarbonyl)-5- azaspiro[2.4]heptane-6-carboxylic acid (1.122 kg, 4.65 mol, 1 equiv.) in anhydrous MeCN (10 L) was charged 4′-iodo bromoacetophenone (1.56 kg, 4.80 mol, 1.032 equiv.). The resulting suspension was charged DIPEA (1.215 L, 1.5 equiv.) at the ambient temperature over the period of about 15 min. Upon the completion of the DIPEA addition, the reaction was slightly exothermic (the internal temperature increased up to 25C) and the reaction mass became a clear solution. The reaction was complete within a couple of hours as indicated by HPLC (99+% conversion). It was rotavapped down, solvent swapped to EtOAc (11 L), subsequently washed with water (3 L), then sodium bicarbonate solution (3 L), and finally with brine (2 L). Upon drying over Na2S04, it was rotavapped to dryness and chased with toluene (4 L x 2) to dryness and finally charged toluene (8 L) to give a solution of the coupled intermediate in toluene (about 86% HPLC purity). ESI MS m/z (M+H)+486.13.

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Bromo-1-(4-iodophenyl)ethanone, and friends who are interested can also refer to it.
