Electric Literature of 69113-59-3, These common heterocyclic compound, 69113-59-3, name is 3-Iodobenzonitrile, its 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.
General procedure: Aryl iodide 3 (0.2 mmol, 1.0 equiv), acrylate/styrene 4 (0.202 mmol, 1.01 equiv), DIPEA (28.4 mg, 0.22 mmol, 1.1 equiv), and Pd(I)-iodo dimer 2 (1.3 mg, 0.0015 mmol, 0.75 mol%) were weighed into a 4 mL screw cap vial, purged with argon, and dissolved in anhydrous toluene(1.5 mL). The vial was capped with a PTFE-lined screw cap and sealed with PTFE tape prior to heating to 100 C under stirring by using an aluminum heating block outside the glovebox. After 15 h, the reaction mixture was allowed to cool to r.t. and diluted with EtOAc (to 20 mL); excess base was quenched by the addition of sat. aq NH4Cl (20 mL). The organic phase was separated and the aqueous layer was extracted with EtOAc (2*20 mL). The combined organic layer was dried over MgSO4 and the solvent was removed under reduced pressure. The obtained crude product was purified by flash column chromatography.
Statistics shows that 3-Iodobenzonitrile is playing an increasingly important role. we look forward to future research findings about 69113-59-3.
