3416-57-7, The chemical industry reduces the impact on the environment during synthesis 3416-57-7, name is 2-(2-Oxopropyl)isoindoline-1,3-dione, I believe this compound will play a more active role in future production and life.
A solution of 2-(2-oxopropyl)isoindoline-1,3-dione (101.0 g, 500.0 mmol) in 1,1- dimethoxy-N,N-dimethylmethanamine (400 mL) was heated at 70 C for about 16 h. Cooled to ambient temperature, PE (200 mL) was added, the mixture was stirred at ambient temperature for 1 h. The precipitate was collected by filtration. The solids were placed into a 500 ml round-bottom flask, HOAc (120 mL) was added, the mixture was stirred at ambient temperature for 40 mm and filtrated, the filtrate was concentrated to remove HOAc. The residue was recrystallized from EA (150 mL) to give the product as a yellow solid (18 g, 14.0%). MS (ESI, m/e) [M+1] 258.9.
The chemical industry reduces the impact on the environment during synthesis 2-(2-Oxopropyl)isoindoline-1,3-dione. I believe this compound will play a more active role in future production and life.
