Adding a certain compound to certain chemical reactions, such as: 4592-94-3, name is 3-(4-Bromophenyl)-3-oxopropanenitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4592-94-3, Safety of 3-(4-Bromophenyl)-3-oxopropanenitrile
General procedure: A mixture of 1,2-bis(bromomethyl)benzene (1.0 mmol), alpha-cyanoacetophenone (1.0 mmol) and Cs2CO3 (3.0 mmol) in DMSO (5 mL) was stirred at 80 C for 4 h till almost full conversion of the substrates by TLC analysis. The resulting mixture was dropped into 100 mL 1 M HCl (aq) and extracted with EtOAc three times (3×50 mL). The organic extract was dried with Na2SO4, filtered and concentrated. The crude product was purified by column chromatography on silica gel (eluent: petroleum ether/EtOAc=50/1) to afford the product 3aa as a white solid.
