标题 :Process for the synthesis of nitrite ion-containing 1:1 complexes of cobalt and metallizable monoazo or azomethine compounds and such complexes

摘要:By metallization of metallizable monoazo or azomethine dyes with cobalt-donating compounds in the presence of a nitrite, especially NaNO 2 , 1:1 cobalt complexes containing a nitrite ion are obtained in a high degree of metallization which can be reacted with metallizable monoazo or azomethine dyes to give very homogeneous 2:1 cobalt complexes in a high degree of purity. This is particularly advantageous when asymmetrical 2:1 cobalt complexes are to be prepared. The process is particularly useful for the preparation of nitrite ion-containing 1:1 complexes of cobalt and a monoazo compound of the formula ##STR1## wherein X is --OH or --NHR, n wherein R is hydrogen or a substituted or unsubstituted alkyl, cycloalkyl, phenyl or naphthyl group, n Ring A is further unsubstituted or further substituted by at least one halo, nitro or optionally substituted alkyl, alkoxy or sulfamoyl substituent, and n The naphthalene ring is further unsubstituted or further substituted by at least one hydroxy, sulfamoyl or acylamino substituent.
