摘要

It is shown that 2-chloro-3H-indol-3-one 1 and analogues have never actually been isolated and that their reactions, reported over 115 years in 40 papers and 4 patents, are those of more or less impure 2-(2, 2-dichloro-2, 3-dihydro-3-oxoindol-1-yl)-3H-indol-3-one 14. Several reactions of the parent compound and its 5, 5′-dimethyl and 5, 5′-dibromo derivatives are reported, especially a reaction with dry methanol leading to the known ...
