Substitution of diazonium groups in aromatic compounds by halo or cyano groups in the presence of cuprous salts (Sandmeyer reaction), copper powder and hydrochloric or hydrobromic acid (Gattermann reaction) or cupric salts (Komer-Contardi reaction) ... [Pg.203]

The substitution of a primary amino group by a nitro group generally occurs by diazotization and the Sandmeyer reaction. ( Komer and Contardi reaction ) [222], In certain cases, diazonium salt nitrates, when boiled in aqueous solution, are converted to nitrophenols. For example p-toluidine, when diazotized in nitric acid solution, forms nitro-p-cresol after the solution had been brought to the boil (Nolting and E. Wild [203a]) ... [Pg.130]

A nitro group may also become mobile under the influence of a large number of substituents in the same ring. The following reaction was observed by Komer and Contardi [1] as early as 1914 ... [Pg.192]

This explosive (m. p. 285°C) was first obtained by Komer and Contardi [43] in 1909, using the reaction ... [Pg.571]
