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.
