Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 19472-74-3, name is 2-Bromophenylacetonitrile, A new synthetic method of this compound is introduced below., Application In Synthesis of 2-Bromophenylacetonitrile
In a vial, 2-bromophenylacetonitirle (2 g, 10.2 mmol), m-tolylboronic acid (1.66 g, 12.2 mmol) and potassium carbonate (2.82 g, 20.4 mmol) were combined with toluene (15 ml), ethanol (15 ml) and water (5 ml) to give a light brown suspension. The mixture was degassed with argon and then tetrakis(triphenylphosphine)palladium(0) (354 mg, 306 mumol) was added. The reaction mixture was heated to 90 C. and stirred overnight. The resulting cooled mixture was diluted with water and extracted into EtOAc. The organic phase was separated and washed with brine, dried (Na2SO4) and concentrated under reduced pressure. Chromatography (silica gel; 0% to 5% EtOAc in hexanes) provided the title product as a colourless oil (1.82 g; 80%). 1H NMR (300 MHz; CDCl3) delta ppm 2.42 (s, 3H), 3.65 (s, 2H), 7.03-7.62 (m, 8H).
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.
