✦ Synopsis

Indolinonic,

phenylimino-indolinonic and quinolinic to the amino group by arylthiyl, arylsulphinyl, arylsulphonyl and arylsulphonyloxy radicals. The formation of the products aromatic aminoxyls readily react with sulfur-centered radicals, generated upon reaction with p-methylthiophenol are explained by the initial attack of the thiophenol radical onto the NO• function to give an unstable adduct which at room temperature. The main product is the deoxygenated derivative i.e. the corresponding amine. The other decomposes to aminyl and arylsulphinyl radicals. From here the reaction can take two different routes to give the compounds, obtained in low yields, are N-substituted amines and amines substituted in a conjugated position with respect products obtained.
