Synthetic Route of 873-32-5, A common heterocyclic compound, 873-32-5, name is 2-Chlorobenzonitrile, molecular formula is C7H4ClN, 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: A 50-mL Schlenk tube was charged with aryl halide (1.63 mmol), aryl boronic acid (2.61 mmol), KOH (3.26 mmol), complex 17d (0.5 mol %), TBAB (0.5 mol % relative to the aryl halide) and water (2 mL). The sealed mixture was stirred at 120 C until TLC analysis confirmed completion of the reaction (for GC analysis the products were extracted with toluene). The aqueous solution was then extracted with ethyl acetate (3 10 mL). The combined organic phases were dried over MgSO4, filtered and evaporated in vacuo. The residue product was purified by column chromatography on silica gel using a mixture of hexane and ethyl acetate as eluent to yield biaryls 23a-m:
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.
