Hypervalent Iodine Chemistry is the first comprehensive text covering all of the main aspects of the chemistry of organic and inorganic polyvalent iodine compounds, including applications in chemical research, medicine, and industry. Providing a comprehensive overview of the preparation, properties, and synthetic applications of this important class of reagents, the text is presented in the. Hypervalent iodine compounds have been extensively used for a variety of chemical transformations and particularly as oxidative reagents.

This review summarizes the synthetic applications of hypervalent iodine(V) reagents: iodylbenzene, IBX (2-iodoxybenzoic acid), DMP (Dess-Martin periodinane) and pseudocyclic IBX analogs. Application of these reagents allows mild and highly selective oxidative transformations in a facile and environmentally friendly manner. Cyclopropanes and Hypervalent Iodine Reagents: High Energy Compounds for Applications in Synthesis and Catalysis Davinia Fernández González, Filippo De Simone, Jonathan P. Brand, Stefano Nicolai, and Jérôme Waser* Abstract: One of the major challenges faced by organic chemistry is the efficient synthesis of increasingly com-plex molecules.

  These compounds are widely used in organic synthesis as selective oxidants and environmentally friendly reagents. Synthetic uses of hypervalent iodine reagents in halogenation reactions, various oxidations, rearrangements, aminations, C-C bond-forming reactions, and transition metal-catalyzed reactions are summarized and discussed. Chapter 3, the key chapter of the book, deals with the many applications of hypervalent iodine reagents in organic synthesis. Chapter 4 describes the most recent achievements in hypervalent iodine catalysis. Chapter 5 deals with recyclable polymer-supported and nonpolymeric hypervalent iodine reagents.

Synthetic applications of hypervalent iodine reagents by Lee McLaren Download PDF EPUB FB2

Hypervalent Iodine Chemistry is the first comprehensive text covering all of the main aspects of the chemistry of organic and inorganic polyvalent iodine compounds, including applications in chemical research, medicine, and industry.

Providing a comprehensive overview of the preparation, properties, and synthetic applications of this important class of reagents, the text is presented in the. Hypervalent iodine compounds have found wide practical application as versatile, efficient, and sustainable reagents for organic synthesis.

Pseudocyclic hypervalent iodine derivatives are characterized by the presence of additional intramolecular non-covalent coordination at the iodine center, which leads to significant alteration of their physical and chemical properties. This book comprehensively covers iodine, its chemistry, and its role in functional materials, reagents, and compounds.

• Provides an up-to-date, detailed overview of iodine chemistry with discussion on elemental aspects: characteristics, properties, iodides, and halogen bonding • Acts as a useful guide for readers to learn how to synthesize complex compounds using iodine reagents or.

Chapter 3, the key chapter of the book, deals with the many applications of hypervalent iodine reagents in organic synthesis. Chapter 4 describes the most recent achievements in hypervalent iodine.

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. Today, no synthetic chemist can afford to ignore the valuable hypervalentiodine.

Chapter 3, the central chapter of the book, deals with the applications of hypervalent iodine reagents in organic synthesis. Chapter 4 describes the most recent achievements in hypervalent iodine. Introduction of hydrophilic groups, such as carboxyl (COOH), trimethylammonium (+ NMe 3), and sulfonate (SO 3 −), onto the phenyl ring of hypervalent iodine reagents is the most frequently used method to give water-soluble hypervalent iodine reagents.

2-Iodoxybenzoic acid (IBX) is the preferred organo-oxidant to oxidize alcohols to the corresponding carbonyl compounds.

Iodine is atomic num in the 5th period, Gr halogens of the periodic table. Iodine is a large-sized halogen element, easily polarizable, and low in electronegativity.

It forms hypervalent organoiodanes beyond the octet theory by readily extending its valence. For example, hypervalent organoiodane with three ligands is a I-3 type compound as shown in the figure. The unstable, electrochemically generated reagents can also easily be transformed into classic bench‐stable hypervalent iodine reagents through ligand exchange.

The combination of electrochemical and flow‐chemistry advantages largely improves the ecological footprint of the overall process compared to conventional approaches. Two new hypervalent iodine reagents containing furan and thiophene moieties in addition to a carbonyl group in the vicinity of the iodine atom were synthesised and characterised.

The X-ray analysis of both compounds revealed a strong intramolecular contact between the carbonyl oxygen and the hypervalent iodine atom with tosylate as a counter ion. These compounds are widely used in organic synthesis as selective oxidants and environmentally friendly reagents.

Synthetic uses of hypervalent iodine reagents in halogenation reactions, various oxidations, rearrangements, aminations, C–C bond-forming reactions, and transition metal-catalyzed reactions are summarized and discussed.
