, p. 98 - 104 (2007/10/03)
O-Acyl and O-arylsulfonyl derivatives of isatin 3-oximes have been synthesized and their interaction with alcohols and amines has been investigated. It was established that none of the esters of 1-substituted isatin 3-oximes reacted with the indicated nucleophiles. 1-Unsubstituted O-aryl and O-arylsulfonyl derivatives react with amines as acylating agents even at room temperature, but O-acetyl derivatives only on heating. Acylamides or arylsulfamides respectively are formed in this way. O-Acyl derivatives do not react with alcohols at room temperature. Only O-benzoyl derivatives form ethyl benzoate on heating in ethanol. A comparative analysis of mass spectrometric data on the processes of acylation and arylsulfonylation is given.

2-Nitroacetanilides, prepared by alkaline hydrolysis of 1-arylamino-1-methylthio-2-nitroethenes, are converted into isatin (1H-indole-2,3-dione) 3-oximes by treatment with concentrated sulfuric acid or trifluoromethanesulfonic acid at room temperature.
