Book excerpt: There are a lot of books available about the chemistry and biology of sulfur. However, this is the first book with a compilation of all relevant Sulfur containing reagents. Synthetic chemists, most particularly in the medicinal and pharmaceutical chemists, are often called upon to prepare compounds that contain Sulfur as a key structural feature. In the past, this seemed to be a domain for specialists; today every synthetic chemist working in these area is expected to synthesize compounds containing sulfides, sulfates, sulfones, etc. This book offers an important source of information for the selection and handling of the right reagents.
