The Current State of the Problem of the Structure and Reactivity of Aromatic Diazo-compounds

The author, one of the leading investigators of the chemistry of diazo-compounds, describes in this article his views on the structure and reactivity of aromatic diazo-compounds. In the usual sense of the word, this is not a complete review of studies on diazo-compounds; it does not reflect all the numerous data published recently and does not contain a critical analysis of new results obtained in the last decade. The review describes the author's views based on the experimental data from his laboratory. The bibliography comprises 33 references.
