1885-38-7, 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. 1885-38-7, name is (E)-Cinnamonitrile, A new synthetic method of this compound is introduced below.
General procedure: Under a nitrogen atmosphere, a mixture of [RhCl(C2H4)2]2 (1.8 mg,0.0045 mmol) and ligand L1f (3.7 mg, 0.0099 mmol) in toluene(1 mL) was stirred at r.t. for 15 min, at which time arylboronic acid(0.60 mmol) was added, followed by cyanoalkenes (0.30 mmol),aqueous KOH (0.75 M in H2O, 0.20 mL, 0.15 mmol) and toluene(1 mL). The reaction was stirred at 80 C for 12 h, after which thereaction mixture was concentrated in vacuo and purified by silica gelflash column chromatography (petroleum ether/ethyl acetate as eluent)to give the product
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.
