Heteroaromatic Compounds of Sulphur, Selenium, and Tellurium

The organization of this Chapter is a radical change from the arrangement of the corresponding parts of Volume 5. This Reporter has tried to review, from the standpoint of sulphur chemistry rather than of heterocyclic chemistry, the highlights of current work which in the previous Volume comprised Chapters 6, 10, 11, 12, and 13, and parts of Chapters 7 and 8. It is not, of course, comprehensive the main criteria used in selection were novelty, utility, and theoretical interest. 

Two relevant reviews, on meso-ionic ring systems and on selenium-nitrogen heterocycles, have been published and a three-part volume on Thiazole and Its Derivatives has appeared. Parts 1 and 2 of this volume are concerned with the chemistry of thiazole and substituted thiazoles, and the third part contains chapters on meso-ionic compounds, on cyanine dyes, and on selenazoles.

Heterocyclic Citemistry is an annual publication which combines material previously reviewed lo thiee separate SPR volumes - Saturated Heterocyclic Chemistry, Aromatic and Heteroaromatic Chemistry and the heterocyclic sections of Organic Compounds of Sulphur, Selenium, and Tellurium. ... 

This new Specialist Report combines the material previously reviewed in "Saturated Heterocyclic Chemistry", "Aromatic and Heteroaromatic Chemistry", both of which are now discontinued, and "Organic Compounds of Sulphur, Selenium, and Tellurium", which although still thriving has surrendered its heterocyclic parts but will continue to report on / -lactam chemistry. 

The major changes in the format and contents of this volume have been necessitated by economic considerations. Sulphur-containing heteroaromatic compounds which previously were included in these Reports and in the Reports on Aromatic and Heteroaromatic Chemistry are now covered in detail only in the new Reports, Heterocyclic Chemistry . The literature on these compounds has been reviewed up to March 1978 in Volume 5 of this series and thereafter in Volume 1 of the new series. Highlights of the literature of these compounds are given as Chapter 6 of this volume. The organization of the remainder of this volume is essentially the same as that of Volume 5 except that the section on the ylides and carbanionic compounds of selenium and tellurium has been considerably extended and the coverage of Chapter 3, Part III has been extended to include dithiocarbamates, xanthates, and trithiocarbonates.
