Meesin, Jatuporn published the artcileDimerization of 3-Chlorooxindoles Mediated by Potassium Ethylxanthate: Synthesis of Isoindigos, Application In Synthesis of 3052-61-7, the publication is Synlett (2022), 33(14), 1317-1322, database is CAplus.
A novel dimerization of 3-chlorooxindoles I (R1 = H, 5-Br, 5-Me, 6-Cl, 7-F, etc., R2 = H; R1 = H, R2 = Me, H2C:CHCH2, PhCH2) promoted by potassium ethylxanthate to access isoindigo derivatives II is described. The reactions proceeded readily at room temperature in short reaction times. A mechanistic study revealed that the 3-chlorooxindole is initially converted into O-Et S-(2-oxo-2,3-dihydro-1 H-indol-3-yl) dithiocarbonate, which subsequently undergoes dimerization with elimination of carbon disulfide. In almost all cases, anal. pure isoindigos II were isolated in moderate to good yields without a requirement for chromatog. purification
