696-41-3, Name is 3-Iodobenzaldehyde, 696-41-3, belongs to iodides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows.
General procedure: A 25-mL flask was charged with Pd(OAc)2 (1.2 mg, 0.005 mmol), 1-iodo-4-nitrobenzene (1a, 127.0 mg, 0.5 mmol), K2CO3 (141.0 mg, 1.0 mmol), H2O (0.5 mL), and PEG 400 (2.0 mL); the flask was subjected to standard cycles (3 ¡Á) of evacuation and back-filling with dry and pure CO. The mixture was stirred at r.t. for the indicated time. The mixture was poured into sat. aq NaCl (15 mL), acidified to pH 3 with 3 M aq HCl, and extracted with EtOAc (3 ¡Á 15 mL). The solvent was removed from the combined organic phases on a rotary evaporator. The crude product was purified by column chromatography (silica gel, PE-EtOAc-HCO2H, 25:1:1) to afford 2a as a light yellow solid; yield: 75mg (90%); mp 238.0-239.3 C. 1H NMR (400 MHz, DMSO-d6): delta = 13.68 (br s, 1 H), 8.30 (d, J = 8.0 Hz,2 H), 8.14 (d, J = 8.0 Hz, 2 H). 13C NMR (100 MHz, DMSO-d6): delta = 165.9, 150.0, 136.4, 130.7, 123.8.
Statistics shows that 3-Iodobenzaldehyde is playing an increasingly important role. we look forward to future research findings about 696-41-3.
