Available in PDF, EPUB and Kindle. Book excerpt: I have therefore reevaluated the reactivity of [CpV(CO)3H]–, and found that although the 18 electron anionic hydride is not a good hydrogen atom donor, the oxidized 17-electron neutral CpV(CO)3H is an extremely potent one. I have made the reactions with [CpV(CO)3H]– catalytic under H2 (now the reactions are done with an added base). The catalytic reactions that use [CpV(CO)3H]– can enact the exact same transformations that tin does, so I have developed a true catalytic replacement for Bu3SnH.

Available in PDF, EPUB and Kindle. Book excerpt: By combining this reaction with the H• transfer, metalloradicals can often catalyze the formation of radicals from H2. Over the years, the Norton group has studied several transition metal hydride systems and demonstrated their applications in different scenarios. The kinetics and thermodynamics of these systems have been studies in detail, and they are shown be competent hydrogen atom donors to unsaturated organic substrates and to organic radicals. Some of these metal hydrides can be made catalytic under hydrogen pressure, thus providing an atom-economical way to effect radical reactions. Specifically, the thermodynamic properties of the chromium hydride HCpCr(CO)3 have been carefully studied. Based on this information, I developed a Ti/Cr cooperative catalytic system featuring multiple interactions between the two metal systems. Herein are described three applications of this Ti/Cr catalytic system: anti-Markovnikov hydrogenation of epoxides (Chapter 2), reductive cyclization of epoxy enones under H2 (Chapter 3), and aziridine isomerization to allyl amines (Chapter 4).

Book Synopsis Transition Metal Hydrides that Mediate Catalytic Hydrogen Atom Transfers by :
Download or read book Transition Metal Hydrides that Mediate Catalytic Hydrogen Atom Transfers written by and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I have attempted to regenerate these vanadium hydrides by a sequential reduction then protonation of the metalloradical. With HV(CO)4dppe this only produced hydrogen gas, presumably by one electron reduction of HV(CO)4dppe. However, with HV(CO)4dppf this does not readily occur and this hydride could potentially be a catalyst for radical cyclizations. Many radical cyclizations involve vinyl (sp2) radicals. I have shown that both the CpCr(CO)3H and the Co(dmgBF2)2(H2O)2 systems can catalytically perform metal to alkyne hydrogen atom transfers (MAHAT's) and that these reactions can be used to perform radical cyclizations very efficiently.

Download or read book Metal Hydrides written by Gust Bambakidis and published by Springer. This book was released on 1981-12-31 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last five years, the study of metal hydrides has ex panded enormously due to the potential technological importance of this class of materials in hydrogen based energy conversion schemes. The scope of this activity has been worldwide among the industrially advanced nations. There has been a consensus among researchers in both fundamental and applied areas that a more basic understanding of the properties of metal/hydrogen syster;,s is required in order to provide a rational basis for the selection of materials for specific applications. The current worldwide need for and interest in research in metal hydrides indicated the timeliness of an Advanced Study Insti tute to provide an in-depth view of the field for those active in its various aspects. The inclusion of speakers from non-NATO coun tries provided the opportunity for cross-fertilization of ideas for future research. While the emphasis of the Institute was on basic properties, there was a conscious effort to stimulate interest in the application of metal hydrides to solar/hydrogen energy conver sion schemes in land areas where solar energy has promise as a primary energy source. In addition to the lectures, several seminars were given which treated topics of special interest in greater detail.

Book Synopsis Hydrogen Transfer Reactions by : Gabriela Guillena
Download or read book Hydrogen Transfer Reactions written by Gabriela Guillena and published by Springer. This book was released on 2016-09-27 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
