Hofmann—Martius rearrangement

V-Alkylaniline and /V,/V-di alkyl aniline hydrochlorides can be rearranged to C-alkyl anilines by heating the salts to 200—300°C. In this reaction, known as the Hofmann-Martius rearrangement, the alkyl group preferentially migrates to the para position. If this position is occupied, the ortho position is alkylated. [Pg.229]

With excess of Br2, further bromination products of the central ring were obtained. 3-iV-Aryl-2-oxindoles (55) undergo Hofmann-Martius rearrangement under acid-catalysed conditions, in contrast to their 3-0 analogues (Scheme 16).53 The thermal... [Pg.465]

A dramatic effect of a counterion on the course of the Hofmann-Martius rearrangement was observed upon thermolysis of /V-benzyl-AkTV-dimethylanilinc hydrochloride 13 and hydroiodide 1632. While the thermolysis of compound 13 gave rise to the dealkylation products 14 and 15 (equation 7), the behavior of the hydroiodide 16 under the same experimental conditions was completely different, leading to the three rearranged products 17-19 (equation 8). [Pg.587]
