Highlighting recent advances in the insertion of sulfur dioxide, providing detailed descriptions of the experimental procedures for these valuable reactions, and discussing the remaining challenges in this field, the brief offers an appealing and highly useful guide for a wide readership in organic chemistry and medicinal chemistry from both academia and industry.
The two-part fifth edition has been substantially revised and reorganized for greater clarity. Among the changes: Updated material reflecting advances in the field since 2001’s Fourth Edition, especially in computational chemistry; A companion Web site provides digital models for study of structure, reaction and selectivity; Solutions to the exercises provided to instructors online.
The material in Part A is organized on the basis of fundamental structural topics such as structure, stereochemistry, conformation and aromaticity and basic mechanistic types, including nucleophilic substitution, addition reactions, carbonyl chemistry, aromatic substitution and free radical reactions. Together with Part B: Reaction and Synthesis, the two volumes are intended to provide the advanced undergraduate or beginning graduate student in chemistry with a sufficient foundation to comprehend and use the research literature in organic chemistry.
Ultrasound scanning yields a series of sectional images. The basis for interpreting
the examination is the individual sectional image. At first
sight, it is easy to be confused by the variable appearance of an ultrasound
scan of the same region in different patients. This has numerous
causes, including differences in density, body fat, age-related differences,
overlying gas, and artifacts. In most cases the apparent discrepancies
are not based on true anatomical differences. When a systematic
scanning routine is closely followed, series of sectional images can be
obtained in every patient with remarkable consistency. Even if the
images themselves vary, the anatomical relationships that are demonstrated
While some excellent atlases have been published on computed tomography
and magnetic resonance imaging, it is curious that no one (to the
author’s knowledge) has taken the trouble to create a similar atlas of
sectional anatomy for abdominal ultrasound. The present atlas attempts
to fill this gap. In particular, the author hopes to provide the beginner
with a comprehensive guide to the initially confusing world of sonographic
Many have helped in the creation of this book. I wish to thank Dr. Hartwig
Schöndube and Dr. Matthias Geist, who gave me some scans. I also
thank Mrs. Stephanie Gay and Mr. Bert Sender of Bremen for their superb
rendering of the illustrations. I am also grateful to the staff at Thieme
Medical Publishers for enabling me to make this book a reality, with special
thanks to Dr. Antje Schönpflug, Mrs. Marion Holzer, and, of course,
Dr. Markus Becker.
