Rhodium has proven to be an extremely useful metal due to its ability to catalyze an array of synthetic transformations, with quite often-unique selectivity. Hydrogenation, C-H activation, allylic substitution, and numerous other reactions are catalyzed by this metal, which presumably accounts for the dramatic increase in the number of articles that have recently emerged on the topic. P. Andrew Evans, the editor of this much-needed book, has assembled an internationally renowned team to present the first comprehensive coverage of this important area. The book features contributions from leaders in the field of rhodium-catalyzed reactions, and thereby provides a detailed account of the most current developments, including: Rhodium-Catalyzed Asymmetric Hydrogenation (Zhang) Rhodium-Catalyzed Hydroborations and Related Reactions (Brown) Rhodium-Catalyzed Asymmetric Addition of Organometallic Reagents to Electron Deficient Olefins (Hayashi) Recent Advances in Rhodium(I)-Catalyzed Asymmetric Olefin Isomerization and Hydroacylation Reactions (Fu) Stereoselective Rhodium(I)-Catalyzed Hydroformylation and Silylformylation Reactions and Their Application to Organic Synthesis (Leighton) Carbon-Carbon Bond-Forming Reactions Starting from Rh-H or Rh-Si Species (Matsuda) Rhodium(I)-Catalyzed Cycloisomerization and Cyclotrimerization Reactions (Ojima) The Rhodium(I)-Catalyzed Alder-ene Reaction (Brummond) Rhodium-Catalyzed Nucleophilic Ring Cleaving Reactions of Allylic Ethers and Amines (Fagnou) Rhodium(I)-Catalyzed Allylic Substitution Reactions and their Applications to Target Directed Synthesis (Evans) Rhodium(I)-Catalyzed [2+2+1] and [4+1] Carbocyclization Reactions (Jeong) Rhodium(I)-Catalyzed [4+2] and [4+2+2] Carbocyclizations (Robinson) Rhodium(I)-Catalyzed [5+2], [6+2], and [5+2+1] Cycloadditions: New Reactions for Organic Synthesis (Wender) Rhodium(II)-Stabilized Carbenoids Containing both Donor and Acceptor Substituents (Davies) Chiral Dirhodium(II)Carboxamidates for Asymmetric Cyclopropanation and Carbon-Hydrogen Insertion Reactions (Doyle) Cyclopentane Construction by Rhodium(II)-Mediated Intramolecular C-H Insertion (Taber) Rhodium(II)-Catalyzed Oxidative Amination (DuBois) Rearrangement Processes of Oxonium and Ammonium Ylides Formed by Rhodium(II)-Catalyzed Carbene-Transfer (West) Rhodium(II)-Catalyzed 1,3-Dipolar Cycloaddition Reactions (Austin) "Modern Rhodium-Catalyzed Organic Reactions" is an essential reference text for researchers at all levels in the general area of organic chemistry.

Rhodium Catalyzed Hydroformylation

View: 7464

In the last decade there have been numerous advances in the area of rhodium-catalyzed hydroformylation, such as highly selective catalysts of industrial importance, new insights into mechanisms of the reaction, very selective asymmetric catalysts, in situ characterization and application to organic synthesis. The views on hydroformylation which still prevail in the current textbooks have become obsolete in several respects. Therefore, it was felt timely to collect these advances in a book. The book contains a series of chapters discussing several rhodium systems arranged according to ligand type, including asymmetric ligands, a chapter on applications in organic chemistry, a chapter on modern processes and separations, and a chapter on catalyst preparation and laboratory techniques. This book concentrates on highlights, rather than a concise review mentioning all articles in just one line. The book aims at an audience of advanced students, experts in the field, and scientists from related fields. The didactic approach also makes it useful as a guide for an advanced course.

Rhodium-catalyzed C-H amination

These valuable insights enabled the development of two robust and important new methods. First, a method was developed to selectively aminate alpha-ethereal C-H bonds, forming N,O-acetals that can be coupled to a variety of nucleophiles. Second, an intermolecular version of the sulfamate insertion reaction was developed to provide access to benzylic amines in one step. The mechanism of this intermolecular C-H amination reaction was investigated and as with the intermolecular reaction, a nitrenoid species was implicated as the active oxidant. Analytical work also uncovered a competing radical-based pathway that leads to catalyst decomposition and undesired side products. It is anticipated that further improvements in catalyst design, coupled with these new mechanistic insights, will enable the continued development of highly efficient and robust C-H oxidation processes.

The metal-catalyzed amination of aryl and alkenyl electrophiles has developed into a widely used methodology for the synthesis of natural products, active pharmaceutical ingredients, agricultural chemicals, and materials for molecular electronics. Copper catalysts promote the coupling of a wide range of nitrogen nucleophiles, including amines, amides, and heteroaromatic nitrogen compounds with aryl and alkenyl halides. The reactivity profile of copper catalysts is complementary to that of palladium catalysts in many cases. Copper catalysts are highly effective with less nucleophilic nitrogen nucleophiles, such as amides and azoles, whereas palladium catalysts are more effective with more nucleophilic amine nucleophiles. Copper is an attractive alternative to palladium due to its significantly lower cost. In addition, high activity palladium catalysts require expensive and often air-sensitive ligands, whereas the modern copper systems use relatively stable and inexpensive diamine or amino acid ligands. Copper-catalyzed C?N coupling reactions are tolerant of a wide range of functional groups and have been applied to the synthesis of a variety of complex natural products. Significant work has also been done to understand the mechanism of these reactions. Current mechanistic understanding of these methodologies is covered in this monograph. The contents of the book are taken from the comprehensive review of the topic in the Organic Reactions series. Optimal experimental conditions for the amination of aryl and alkenyl halides with all classes of nitrogen nucleophiles are presented. Specific experimental procedures from the literature are provided for the major classes of copper-catalyzed C?N coupling reactions. A tabular survey of all examples of Cu-catalyzed arylation and alkenylation of nitrogen nucleophiles is presented in 35 tables organized by nitrogen nucleophile and electrophilic coupling partner. The literature is covered through December 2015 and provides 300 recent citations to supplement the 680 citations of the original hardbound chapter. These latest literature references have been collected in separate sections according to the sequence of the tables in the tabular survey section. In each of the sections, the individual citations have been arranged in alphabetic order of the author names. Copper-Catalyzed Amination of Aryl and Alkenyl Electrophiles is intended to provide organic chemists with an accessible, but detailed, introduction to this important class of transformations.
