The chemical industry reduces the impact on the environment during synthesis 317-20-4, name is 7-Fluoroisatin, I believe this compound will play a more active role in future production and life. 317-20-4
General procedure: The mixture of isatin (1 mmol), 3-amino-1-phenyl-1H-pyrazol-5(4H)-one (1 mmol), 1,2-diarylethan-1-one, 2,3-dihydroinden-1-one (1 mmol) or 3,4-dihydronaphthalen-1(2H)-one (1 mmol), H2O (6 mL), HOAc (2 mL) was put in a reaction flask under 90 C about 5-7 h (monitored by TLC). After completion, the reaction mixture was cooled to room temperature and the products would be isolated out at same time. Then, compound 4 was recrystallized from DMF, however, the pure products of 6 and 8 were filtered from water, dried, without further recrystallization.
The chemical industry reduces the impact on the environment during synthesis 317-20-4. I believe this compound will play a more active role in future production and life.
