Adding a certain compound to certain chemical reactions, such as: 60434-13-1, name is 5-Chloro-1-methylindoline-2,3-dione, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 60434-13-1, COA of Formula: C9H6ClNO2
General procedure: A solution of N-methylisatin (322 mg, 2.0 mmol), phenylacetylene (306 mg, 3.0 mmol), CuI (76 mg, 0.4 mmol), and Cs2CO3 (978 mg, 3.0 mmol) in CH3CN (4.0 mL) was stirred at room temperature for 18 h. After aqueous extractive workup and column chromatographic purification process (CH2Cl2/EtOAc, 15:1) 1a was obtained as a pale yellow solid, 347 mg (66%).1-12 Other compounds were prepared similarly,1-12 and the propargylic alcohols were used in the next hydrogenation step without further identification process.
