Synthetic Route of 7147-90-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 7147-90-2, name is 5-Chloroisoindoline-1,3-dione, This compound has unique chemical properties. The synthetic route is as follows.
To a solution of 5-chloro-isoindole-l,3-dione (3.63 g, 20 mmol) in DCM (150 mL) was added benzylmagnesium chloride (2 M in THF, 30 mL) dropwise at 0 C. After the addition, the reaction mixture was allowed to stir at 0 C for 3 hours before it was quenched with satd. aq. NH4C1 solution. After extraction with DCM, the organic layer was washed with brine, dried over anhy. Na2S04, filtered and concentrated in vacuo to give a crude product containing a mixture of two regio isomers (5.47 g, 100%). MS: 274.1 (M+H+).
The chemical industry reduces the impact on the environment during synthesis 5-Chloroisoindoline-1,3-dione. I believe this compound will play a more active role in future production and life.
