First published in 1971 this volume claims that nitration is important for two reasons. First, because it is the most general process for the preparation of aromatic nitro-compounds, and secondly, on account of the part it has played in the development of theoretical organic chemistry. The special concern of this monograph is with those nitrating systems in which mechanistic studies have established, or made probable, the identity of the agent through which they effect nitration. It presents a summary of the understanding of the nitration process. A discussion of the various types of nitrating systems leads to the conclusion that nitration is generally effected through the nitronium ion. The mechanism of the substitution is examined, and discussed in terms of reactivity for particular groups of aromatic compounds.

Azoles are five-membered cyclic compounds containing one or more heteroatoms in the ring, at least one of which must be nitrogen. The rings contain the maximum number of non-cumulative double bonds consistent with the normal valencies of the ring atoms. This 1976 volume sets out in detail the structure and properties of these compounds and their derivatives. After an introduction and a section dealing with general physical properties there is an extensive discussion of electrophilic and nucleophilic substitution reactions. This is followed by a description of the types of reaction which modify the nucleus of the azole family. A short section on photochemical reactions compares those reactions which are not easy to classify with the thermolyses discussed in the previous chapter. To complete the work there is an extensive discussion of the properties of functional side groups and an extensive bibliography detailing about 1500 publications on azole chemistry.
