A characteristic property of most diazotizations of aminoazoles is the occurrence of a relatively stable transient intermediate (probably the A-nitrosoamine), in contrast with the diazotization of carbocyclic aromatic amines, where A-nitrosoamines have been considered to be unstable intermediates. This problem will be discussed in the context of the mechanism of diazotization in Section 3.4. 

Similar interchange processes may occur in other condensation polymers under suitable conditions. There is ample evidence in the literature on polyamides, and on monomeric amides as well, for the occurrence of the amine-amide interchange reaction (II)...
