Catalyst

Catalysts are increasingly used by chemists engaged in fine chemical synthesis within both industry and academia. Today, there exists a huge choice of high-tech catalysts, which add enormously to the repertoire of synthetic possibilities. However, catalysts are occasionally capricious, sometimes difficult to use and almost always require both skill and experience in order to achieve optimal results. This series aims to be a practical help for advanced undergraduate, graduate and postgraduate students, as well as experienced chemists in industry and academia working in organic and organometallic synthesis. The series features: Tested and validated procedures. Authoritative reviews on classes of catalysts. Assessments of all types of catalysts. Expertise from the Leverhulme Centre for Innovative Catalysis, Liverpool, UK.The review section in the first volume of the series contains a report by Stanley M. Roberts on the integration of biotransformations into the catalyst portfolio. The procedure section contains a wide variety of synthetic protocols, such as epoxidations of unsaturated ketones and esters, asymmetric reductions of carbon-oxygen double bonds, asymmetric hydrogenations of carbon-carbon double bonds and other types of reaction. The featured catalysts include a wide range of different materials such as poly-D-leucine, D-fructose-based dioxiranes, oxaborolidine borane, some important titanium and ruthenium complexes as well as baker's yeast. For each reaction there are one or several detailed protocols on how to prepare and employ the various catalysts.

Palladium Reagents and Catalysts brings to synthetic organic chemists the many applications of organopalladium chemistry, highlighting the most recent discoveries in this rapidly expanding field. This volume provides a comprehensive overview of the development of many innovative synthetic methods, using palladium reagents either as catalysts or stoichiometric reagents.

Adkins catalyst - The Adkins catalyst is a copper chromite or copper chromium oxide catalyst used in the hydrogenation of ester compounds to the corresponding alcohols. For example, sebacion derived from a intramolecular acyloin condensation of dimethyl sebacate is hydrogenated to 1,2-cyclodecanediol by this catalyst at high hydrogen gas pressure (135 atm) and 150 °C in a so-called hydrogenation bomb.

Post-metallocene catalyst - A post-metallocene catalyst is a kind of catalyst for olefin polymerization. "Post-metallocene" refers to the generation of catalysts following Kaminsky catalysts, which are metallocene catalysts discovered in 1980 by Walter Kaminsky, and have been predominant in the olefin polymerization catalyst area for the past quarter century.

CBS catalyst - The CBS catalyst or Corey-Bakshi-Shibata catalyst is an asymmetric catalyst derived from proline. It finds many uses in organic reactions such as the CBS reduction, Diels-Alder reactions and [3+2] cycloadditions.

Adams' catalyst - Adams' catalyst was named for Roger Adams and is a reagent represented as platinum(IV) oxide hydrate, PtO2-H2O. It is a heterogeneous hydrogenation catalyst, for the reduction and/or hydrogenolysis of susceptible groups.
