Application of 7477-63-6, 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. 7477-63-6, name is 7-Chloroisatin, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: A mixture of isatins 1a-f (1 mmol), active cyanomethanes 2a-b (1 mmol), and enolizable ketones 3a-d (1 mmol) in ethanol (3 ml)was stirred at room temperature in the presence of HIL (Scheme 2).The reaction progress was monitored by thin-layer chromatography (TLC). After completion of the reaction, the reaction mixture was treated with ethanol to recover the insoluble catalyst by filtration.The filtrate was then concentrated under vacuum and the desired product was obtained. The structures of the products were confirmed by 1H NMR, IR spectroscopy, and supported by elemental analysis. The filtered catalyst was dried under vacuum for 2 h and was reused with a fresh charge of solvent and reactants for subsequent runs under the same reaction conditions to observe its catalytic efficiency.
The chemical industry reduces the impact on the environment during synthesis 7-Chloroisatin. I believe this compound will play a more active role in future production and life.
