Reference of 6341-92-0,Some common heterocyclic compound, 6341-92-0, name is 6-Chloroisatin, molecular formula is C8H4ClNO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: A mixture of phthalic anhydride (1 mmol), isatin (1 mmol), malononitrile(1 mmol), hydrazine (1 mmol), and Fe3O4dipyridineMNPs (0.0008 g) was stirred at room temperature under solvent free conditions for 50 min. Upon completion, the progress of the reaction was monitored by TLC when the reaction was completed,EtOH was added to the reaction mixture and the Fe3O4methyleneMNPs was separated by external magnet. Then the solvent was removed from solution under reduced pressure and the resultingproduct purified by recrystallization using ethanol.

The synthetic route of 6341-92-0 has been constantly updated, and we look forward to future research findings.

In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6341-92-0, name is 6-Chloroisatin belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. Quality Control of 6-Chloroisatin

General procedure: A mixture of substituted isatin (12.3 mmol), hydrazine hydrate (368 mmol), potassium hydroxide (245 mmol), and ethylene glycol (242 mmol) were heated at 100 C for 1 h. The reaction mixture was cooled on ice bath and acidified using concd HCl (drop wise addition) along with vigorous stirring. The precipitated product was vacuum filtered and washed with hexanes to give substituted indolin-2-ones in 90-95% yield.

The synthetic route of 6341-92-0 has been constantly updated, and we look forward to future research findings.

6341-92-0, 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. 6341-92-0, name is 6-Chloroisatin, This compound has unique chemical properties. The synthetic route is as follows.

General procedure: Microwave Heating: diversity of substituted indoline-2,3-dione 2 (1.0 mmol) was introduced in a 10-mL Initiator reaction vial, diversity of substituent alpha-thiocyanatoethanone 1 (2.0 mmol), EtOH (1.0 mL), and sodium hydroxide (1.0 mmol, 0.040 g) were then successively added. Subsequently, the reaction vial was capped and then pre-stirred for 20 s. The mixture was irradiated (time: 10 min, temperature: 80 C; Absorption Level: High; Fixed Hold Time) until TLC (petroleum ether: acetic ether 3:1) revealed that conversion of the starting material 2 was complete. The reaction mixture was cooled to room temperature. Next, the system was diluted with cold water (20 mL) and neutralized by diluted acidic solution. The solid product was collected by Buechner filtration and was purified by recrystallization from 95% ethanol to afford the pure yellow solid (3a-z)
