Iodoaniline has been prepared by the reduction of -nitro-iodobenzene 1 by the hydrolysis of -iodoacetanilide formed by the action of iodine monochloride on acetanilide 2 and by the direct iodination of aniline.3 The method described here is an adaptation of the procedure used by Wheeler/ and by Hann and Berliner 5 for the iodination of the toluidines.

Apart from Hofmann and Caro, several German chemists and colorists who had worked in the English aniline dye industry returned to their homeland from the mid-1860s. Some, however, did not. Among the latter was Ivan Levinstein (Figure 10), who emigrated from Berlin to Salford, near Manchester, in 1864, and set up in business to manufacture aniline, its salts, and aniline red and derivatives. Soon he moved to Blackley, Manchester, to found what in 1926 would become a major facility of Imperial Chemical Industries (ICI). 

Martius, by now a partner in the AGFA firm of Berlin, obtained a sample of chrysoidine (18) and handed it over to his consultant, A.W. Hofmann (Figure 11), for scientific investigation. In January 1877, Hofmann published details of the constitutions, as well as the methods of preparation, for 18, phenylene brown (15) and the related aniline yellow (16), much to the chagrin of Caro and his colleagues33-36. Soon it was shown that phenylene, or Bismarck brown (15), was in fact a bisazo compound 15a (Scheme 6). 

Modem Chemistry (1865). In fact, this textbook provided a brilliant summary of the emerging theory of chemical stmcture and strongly influenced the university teaching of chemistry. Hofmann became professor at the University of Bonn in 1864 and at the University of Berlin from 1865, and was a founder (1868) of the Deutsche Chemisette Gesellschaft and its journal Berichte . He studied further aniline chemistry and was the first to prepare, among others, rosaniline and its derivatives.
