Synthetic Route of 4387-36-4, A common heterocyclic compound, 4387-36-4, name is 2-Iodobenzonitrile, molecular formula is C7H4IN, 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: An oven dried two-necked round bottom flask was charged with aryl halide (1mmol) and K3PO4 (2mmol), evacuated and backfilled with argon. The azole compound (1mmol) and 2mL of DMSO were added under argon. After that Cu-NP (1.6mmol) was added and the flask was again backfilled with argon. The flask was then immersed in a preheated oil bath at 80°C until the conversion was completed (detected by TLC). The cooled mixture was partitioned between ethyl acetate (10mL) and saturated NH4Cl (10mL). The aqueous layer was extracted with ethyl acetate (2×10mL), the organic layer was washed with brine (20mL), dried over anhydrous Na2SO4 and concentrated in vacuum. The residue was purified by column chromatography on silica gel using ethyl acetate in hexane (1.5?10percent) as eluent to afford the desired product. All the products have been characterized by 1H NMR, 13C NMR, and mass spectroscopy. For new products, FTIR data were also recorded.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
