Carbon-carbon Bond Forming Reactions Facilitated by Kukhtin-ramirez Adducts

Languages : en
Pages :
Book Description
The preparation of carbon-carbon bonds is an essential goal of organic synthesis. This thesis describes research efforts directed toward the use of Kukhtin-Ramirez type oxyphosphoranes derived from [alpha]-ketoesters as reagents to initiate carbon-carbon bond formation in three transformations. First, a non-metal mediated Barbier-type addition is described with diastereoselection under both substrate and reagent control. Second, diastereoselective epoxidation resulting from reaction of Kukhtin-Ramirez adducts with aldehydes is described and the impact of Lewis acid additives on diastereoselection is explored. Third, the potential of Kukhtin-Ramirez adducts as carbene transfer precursors in transition metal-catalyzed reactions is investigated within the context of cyclopropanation and insertion reactions. Concisely, this thesis explores the ambiphilic properties of Kukhtin-Ramirez adducts by attempting to carry out new carbon-carbon bond forming reactions.

Cleavage of Carbon-Carbon Single Bonds by Transition Metals
Author: Masahiro Murakami
Publisher: John Wiley & Sons
ISBN: 352768011X
Category : Technology & Engineering
Languages : en
Pages : 292
Book Description
Edited by leading experts and pioneers in the field, this is the first up-to-date book on this hot topic. The authors provide synthetic chemists with different methods to activate carbon-carbon sigma bonds in organic molecules promoted by transition metal complexes. They explain the basic principles and strategies for carbon-carbon bond cleavage and highlight recently developed synthetic protocols based on this methodology. In so doing, they cover cleavage of C-C bonds in strained molecules, reactions involving elimination of carbon dioxide and ketones, reactions via retroallylation, and cleavage of C-C bonds of ketones and nitriles. The result is an excellent information source for researchers in academia and industry working in the field of synthetic organic chemistry, while equally serving as supplementary reading for advanced courses in organometallic chemistry and catalysis.

Category : Science
Languages : en
Pages : 268
Book Description
"Cross-Coupling Reactions: An Overview opens with an overview of the fundamentals and applications of the young and fast developing area of transition metal catalyzed/mediated oxidative (dehydrogenative) C-H/C-H coupling reactions between two (hetero)arenes. Continuing, the authors highlight the recent advances regarding the ligand supported transition metal-catalyzed domino (cascade) or one-pot syntheses of various heterocycles involving cross-coupling reactions. The recent advances in Cu catalyzed tandem reactions for heterocycle synthesis are also addressed. Cu metal chemistry has garnered attention as a potential alternative to precious transition metals, being cheaper, more sustainable and more easily available. A comprehensive account of research on green chemical routes is provided, involving various palladium metal-based catalysts utilized in facilitating cross-coupling reaction in aqueous media. Reported decarboxylative cross-coupling reactions are discussed along with suitable examples, focusing on their mechanism of action"--

Development of Neutral Redox Carbon-carbon Bond Forming Reactions Via Transition Metal-catalyzed Transfer Hydrogenation
Author: Khoa Dang Nguyen (Ph. D.)
Publisher:
ISBN:
Category :
Languages : en
Pages : 1316
Book Description
Since C-C bonds form the backbone of every organic molecule and reside at the heart of chemical science, the development of new efficient methods for promoting C-C bond formation is of great significance. Inspired and expanded from traditional Grignard reactions, the work presented in this dissertation focuses on metal catalyzed neutral redox-triggered carbonyl addition via transfer hydrogenation. Advancing the native reducing capability of alcohols, employment of catalytic transition metals enables the formation of nucleophile-electrophile pairs in situ, en route to the products of formal alcohol C-H functionalization. These redox-triggered reactions circumvent the stoichiometric metallated byproduct waste and streamline the construction of complex molecules from simple and/or readily available feedstocks. The research reported herein discloses new developed methodologies of ruthenium and iridium catalyzed coupling reactions of primary and secondary alcohols with various pi-unsaturates. These studies contribute to the growing body of redox-triggered alcohol C-C couplings - new carbonyl addition chemistry that extends beyond the use of premetalated reagents.
