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. 56341-37-8, name is 6-Chlorooxindole, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C8H6ClNO
EXAMPLE 20c; Preparation of intermediate E/Z-3-[4-Chloro-2-(6-chloro-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-phenoxy]-2,2-dimethyl-propionic acid methyl ester; 3-(4-chloro-2-formyl-phenoxy)-2,2-dimethyl-propionic acid methyl ester (6.7 g, 25 mmol) and 6-Chloro-1,3-dihydro-indol-2-one (4.35 g, 25 mmol) were mixed in 20 mL of anhydrous methanol. Then pyrrolidine (2 mL, 25 mmol) was added dropwise at r.t. The mixture was heated to 70 C. for 3 h and cooled to room temperature. The precipitate was collected by filtration and dried to give title compound as yellow solid (Yield: 7 g, 67%).m/z (M+H)+: 420
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 56341-37-8.
