Abstract
Process for the preparation of new diazoamino compounds characterized in that a 1-aminobenzole-2-carboxylic acid-4-sulphonic acid of the formula is condensed in which z = v means a methyl group or benzyl group z = w a straight alkyl radical with 2-4 carbon atoms linked by a carbon atom in the final position with -nh- with a diazo compound of an aminalibre of hydro-solvent power groups of formula ** in which r represents a radical of benzolesting both x and h in ortho position with respect to the aminox group a hydrogenation atom group u of the composition -omn-1 cn h2n 1 (to which effect myn means both whole numbers by value of at most 2y mn at most 2) or a chlorine atom because the starting materials are chosen for this purpose so that the vapor pka of the amine differs from cx; z by at most plus minus 0.7importing cx = h; z = v) = 4. 8cx = h; z = w) = 4.2cx = u; z = v) = 4.0cx = u; z = w) sub> = 3.5cx = cl; z = v) = 3.6cx = cl; z = w) = 2.9 (Machine-translation by Google Translate, not legally binding)
