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. 181765-86-6, name is Methyl 5-bromo-2-iodobenzoate, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 181765-86-6
This procedure was adapted from Marcoux el al.1Methyl 5-bromo-2- iodobenzoate (750 mg, 2.20 mmol), phenol (104 mg, 1.10 mmol), Cs2C03(717 mg, 2.20 mmol), (CuOTf)2PhH (27.7 mg, 0.0550 mmol), 1 -naphthoic acid (284 mg, 1.65 mmol), and 4A molecular sieves (625 mg) were suspended in anhydrous toluene (2.5 mL) in a vial. The vial was sealed, and the mixture was degassed with N2for 7 minutes and heated at 110 C for 18 hours. The reaction mixture was filtered through a pad of celite, and the filtrate was diluted with EtOAc (100 mL) and washed with brine (100 mL). The organic phase was dried over anhydrous Na2S04and concentrated under reduced pressure. Purification by flash column chromatography (hexanes to 85: 15 hexanes/EtOAc) afforded 12a as a yellow oil (300 mg, 89% yield). Rf= 0.46 (hexanes/EtOAc 90: 10 v/v). NMR (400 MHz, CDCl3) delta 8.03 (d, J = 2.3 Hz, 1H), 7.54 (dd, J= 8.8, 2.4 Hz, 1H), 7.34 (t , J= 7.5 Hz, 2H), 7.11 (t, J= 7.4 Hz,1H), 6.96 (d , J= 8.5 Hz, 2H), 6.85 (d, J= 8.8 Hz, 1H), 3.82 (s, 3H).13C NMR (101 MHz, CDCI3) delta 165.0, 157.2, 155.7, 136.5, 134.6, 130.0, 124.7, 123.8, 122.4, 118.5, 115.9, 52.6.MS (ESI+) calculated for [Ci4Hi2Br03]+[M+H]+, 307.0; found 307.0.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 181765-86-6.
