Related Products of 6293-83-0, 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. 6293-83-0 name is 2-Iodo-4-nitroaniline, 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: In a typical reaction, PdCl2(PPh3)2 (88 mg, 0.125 mmol), CuI (24 mg, 0.125 mmol) and THF (5 ml) were placed in an oven-dried, 2-neck RB flask. To this suspension, 2-iodoaniline (5.47 mg, 2.5 mmol) and triethylamine (702 mul, 5.0 mmol) were added. The reaction mixture was degassed by bubbling with argon for 15 min. Phenylacetylene (300 mul, 2.75 mmol) was then added, and the reaction mixture stirred at RT. After complete consumption of the 2-iodoanilines (~2 h, by TLC), the reaction mixture was filtered through celite, and the solvent rotary evaporated to obtain the crude product which was purified by silica gel (60-120 mesh) column chromatography using ethylacetate/ hexane (1:9, v/v) as eluent to give pure 2-phenylethynylaniline, 2a (400 mg, 83%).
