The essential new edition of the book that put hypercarbon chemistry on the map A comprehensive and contemporary treatment of the chemistry of hydrocarbons (alkanes, alkenes, alkynes, and aromatics) towards electrophiles, Hypercarbon Chemistry, Second Edition deals with all major aspects of such chemistry involved in hydrocarbon transformations, and of the structural and reaction chemistry of carboranes, mixed hydrides in which both carbon and boron atoms participate in the polyhedral molecular frameworks. Despite the firmly established tetravalency, carbon can bond simultaneously to five or more other atoms. "Hypercarbon" bonding permeates much organic, inorganic and organometallic chemistry, and the book serves as the compendium for this phenomenon. Copious diagrams illustrate the rich variety of hypercarbon structures now known, and patterns therein. Individual chapters deal with specific categories of compound (e.g. organometallics, carboranes, carbocations) or transformations that proceed through transient hypercarbon species, detailing fundamental chemistry, including reactivity, selectivity, stereochemistry, mechanistic factors and more.

This book is a volume in the Penn Press Anniversary Collection. To mark its 125th anniversary in 2015, the University of Pennsylvania Press rereleased more than 1,100 titles from Penn Press's distinguished backlist from 1899-1999 that had fallen out of print. Spanning an entire century, the Anniversary Collection offers peer-reviewed scholarship in a wide range of subject areas.

This revised edition of Seeking Security in an Insecure World provides a thorough, accessible introduction to contemporary security studies. All chapters are updated and a wide range of new topics are discussed, including the Syrian civil war, Russia’s annexation of Crimea and its intervention in East Ukraine, the global refugee crisis, China’s military buildup, the impact of fracking on oil and gas markets, and rapidly evolving cyberwar capabilities. Each chapter also addresses what has been and can be done to enhance security. Overall, Seeking Security in an Insecure World offers a clear and compelling framework for understanding what security means today and how it can best be achieved.
