Advances heteroaromatic compounds

The first detailed survey of the prototropic tautomerism of heteroaromatic compounds appeared in four chapters in Volumes 1 and 2 of Advances in Heterocyclic Chemistry published in 1963. In 1976, a monograph entitled The Tautomerism of Heterocycles was issued as Supplement 1 to Advances in Heterocyclic Chemistry to update the work published in 1963. 

Thus the overall picture of homolytic substitution of heteroaromatic compounds has undergone only minor modification as regards arylation, but very great modification as regards substitution with nucleophilic radicals, since Norman and Radda reviewed the field in these Advances.

Volume 72 of Advances in Heterocyclic Chemistry consists of six chapters. The first considers the role of five- and six-membered heteroaromatic compounds as ct and ir ligands. Authored by Professors A. D. Garnovskii (Rostov-on-Don, Russia) and A. P. Sadimenko (Fort Hare, South Africa), it gives an overview of the multitude of structural types that can arise when heterocycles are used as ligands in organometallic derivatives. Many such compounds are of great industrial importance in catalytic and other processes. No previous comprehensive overview of this subject has been available. 

The longest chapter of this volume, authored by Roger Gallo and Christian Roussel (France) and Ulf Berg (Sweden), gives a comprehensive account of the quantitative treatment of steric effects in heteroaromatic compounds—a subject that has been advanced significantly by these authors. Finally, V. N. Charushin and O. N. Chupakhin (USSR) and H. C. van der Plas (The Netherlands) review reactions of azines with bifunctional nucleophiles.
