Abstract
250,819. Imray, O. Y., (Soc. of Chemical Industry in Basle). Sept. 11, 1925. Nuclear substitution products of diphenylamine are prepared by causing a nuclear halogen substitution product of a benzene hydrocarbon to act on an alkali-metal compound of a primary aromatic amino-body of the benzene series, if desired in presence of a catalyst, either one or both of the reacting substances containing at least one nuclear substituent in addition to the halogen atom or amino group. In an example, o-o<1>-ditolylamine is obtained by heating o-toluidine with sodium and o-chlortoluene in the presence of copper powder as a catalyst. In a similar manner, o-tolylphenylamine may be obtained from ochlortoluene and aniline or from o-toluidine and brombenzene, o-p-ditolylamine from p-chlortoluene and o-toluidine, and 4<1>-chlor-o-o<1>-ditolylamine from 2: 5-dichlortoluene and o-toluidine.
