The Wolff-Kishner Reduction and Related Reactions: Discovery and Development offers a detailed discussion of this reaction, its discoverers, and its development since its discovery. Derivative name reactions-including the Wharton and Shapiro reactions-are also discussed. The book is illustrated with examples from literature and corresponding references to the primary literature to aid further reading. It provides a comprehensive review of the century of chemistry that allows the reader to follow the development of this important synthetic reaction. In addition, it provides biographical details on the chemists who discovered and developed the reaction, thus adding a human dimension to the discussion.
Introduces Wolff and Kishner, the discoverers of the reaction, along with Huang Ming-Long, the developer of an important modification of the reaction Discusses the discovery of the reaction and the way that priority for the discovery was settled between Wolff and Kishner Discusses, in depth, the development and usage of the reaction over the century, from its discovery, to its most recent applications and modifications in synthesis Includes biographical materials on the chemists responsible for major derivative name reactions based on the Wolff-Kishner reduction

In the wake of Hurricane Katrina, many questioned whether the large number of political appointees in the Federal Emergency Management Agency contributed to the agency''s poor handling of the catastrophe, ultimately costing hundreds of lives and causing immeasurable pain and suffering. The Politics of Presidential Appointments examines in depth how and why presidents use political appointees and how their choices impact government performance--for better or worse. One way presidents can influence the permanent bureaucracy is by filling key posts with people who are sympathetic to their policy goals. But if the president''s appointees lack competence and an agency fails in its mission--as with Katrina--the president is accused of employing his friends and allies to the detriment of the public. Through case studies and cutting-edge analysis, David Lewis takes a fascinating look at presidential appointments dating back to the 1960s to learn which jobs went to appointees, which agencies were more likely to have appointees, how the use of appointees varied by administration, and how it affected agency performance. He argues that presidents politicize even when it hurts performance--and often with support from Congress--because they need agencies to be responsive to presidential direction. He shows how agency missions and personnel--and whether they line up with the president''s vision--determine which agencies presidents target with appointees, and he sheds new light on the important role patronage plays in appointment decisions.

The organic chemists of Russia during the pre-revolutionary period included some of the most creative and talented chemists of the nineteenth and early twentieth centuries. Indeed, this is attested by the number of reactions and empirical rules bearing their names. This volume is of interest for both historians of chemistry and organic chemists wishing to discover more about the historical development of their discipline in Russia. From the founding of the Russian Academy of Sciences by Peter the Great in 1725 to the early years of the nineteenth century, Russian organic chemistry was largely in the hands of foreign scientists. However, the Russification of organic chemistry in Russia had begun before the middle of the nineteenth century, and reached its zenith during the last half of the same century, by which time vibrant schools of chemistry had arisen in the eastern city of Kazan'', at Moscow and at St. Petersburg. By the end of the century, the Chairs of organic chemistry at universities throughout the Russian empire were occupied by Russian chemists, almost half of them trained at Kazan''. This volume discusses the contributions of these organic chemists which include: the structural theory of organic chemistry, empirical rules for addition and elimination, reactions involving carbon nucleophiles, such as the aldol reaction and alcohol synthesis using organozinc nucleophiles, the discovery of sulfoxides and sulfonium salts, and a range of important redox reactions.
