Adding a certain compound to certain chemical reactions, such as: 139512-70-2, name is 4-Chloro-5-fluorobenzene-1,2-diamine, belongs to chlorides-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 139512-70-2, category: chlorides-buliding-blocks
General procedure: A mixture of compounds 1a-l (0.013 mol) and 4-chloro-5-fluoro-ophenylenediamine(2) (0.01 mol) in methanol (10 mL) was irradiatedwith ultrasonic irradiation at 50 C for 7 min (8 min for 3a) Afterreaction completion (monitored by TLC, ethyl acetate/hexane = 3:1), themixture was poured onto water and the precipitated product was filtrated off, washed with water and recrystallised from ethanol/water, 3:1.
