This book, written by the eminent Russian organic chemist Professor M. G. Voronkov, exhaustively deals with the reactions of sulfur with organic compounds. It is the only book on the subject which covers both work readily available to Western scientists and research carried out by Russian workers. Since much of the work discussed in this volume is not readily accessible to Western scien­ tists, it will enable them to find hitherto "unpublished" research. In addition, Professor Voronkov has dealt with many reactions and processes of interest to the industrial chemist; e.g., there is an interesting section on sulfur dyes and related compounds, and the chemistry of vulcanization is lucidly discussed. Hence this book should be of value to both academic and industrial chemists inter­ ested in the chemistry and reactions of sulfur, and also to those synthetic chemists studying new pathways to organic compounds. The text has recently been updated and revised, and there are numerous references to publications up to and including 1980. An exhaustive index is provided to enable the reader to refer rapidly to any of the compounds, reactions, or processes discussed in the text.
