Opis

This book describes the fascinating chemistry of the many kinds of organic compounds of hypervalent iodine. Each chapter deals with a particular iodine compound or families of compounds which have been used as reagents in a plethora of useful transformations. These include assorted oxidation, such as with the precious Dess-Martin reagent as well as with a wide range of further reactions. Prominent features of hypervalent iodine reagents derived from iodobenzene are: ready availability, operational simplicity, mild reaction conditions, and high efficiency. They are environmentally safe and can be recycled. New species may be easily prepared by introducing substituents in the benzene ring or changing the ligand attached to iodine. Their combination with other reagents broadens considerably their synthetic potential. Today, no synthetic chemist can afford to ignore the valuable hypervalentiodine reagents.

• Features up-to-date coverage of a wide range of topics
• Includes many tables featuring a diversity of reactivity, and a comprehensive index
• Acts as a comprehensive, up-to-date reference on all aspects of hypervalent iodine chemistry
• Contains a section on unusual efficiency of hypervalent iodine reactions

Recenzje

"I suspect there will be no synthetic chemist who, after reading this book, will not try to include the valuable hypervalent iodine reagents in their synthetic plans." --Andrew N. Boa in CHEMISTRY IN BRITAIN

O autorze

Anastasios Varvoglis obtained his Ph.D. from Cambridge University, UK. He has been professor of organic chemistry at the University of Thessaloniki, Greece since 1974, and has several articles and a book published in the field of hypervalent iodine. Alan Katritzky was educated at Oxford and has held faculty positions at Cambridge and East Anglia before he migrated in 1980 to the University of Florida, where he was Kenan Professor and Director for the Institute for Heterocyclic Compounds. During his career he has trained more than 1000 graduate students and post-docs, and lectured and consulted world-wide. He led the team, which produced "Comprehensive Heterocyclic Chemistry” and its sequels, "CHEC-II" and "CHEC-III”, has edited "Advances in Heterocyclic Chemistry, Vols. 1 through 111” and conceived the plan for "Comprehensive Organic Functional Group Transformations”. He founded Arkat-USA, a non-profit organization which publishes "Archive for Organic Chemistry” (ARKIVOC) an electronic journal completely free to authors and readers at (www.arkat-usa.org). Honors include 14 honorary doctorates from 11 countries and membership of foreign membership of the National Academies of Britain, Catalonia, India, Poland, Russia and Slovenia.
