Abstract:

This thesis is presented as five chapters: Chapter 1.0 is divided into two sections: the first is a review of palladium-catalysed C–C bond forming reactions. It covers palladium-catalysed cross-coupling reactions; C–H bond functionalisation; the Heck reaction and functionalisation of heteroaromatic C–H bonds. Secondly the use of tetrahydropyridines in organic synthesis is discussed, with a particular focus on methodology developed by the Craig group. Chapter 2.0 discusses the research carried out during this studentship. It is divided into six sections and discusses the results obtained from r

Ce travail de thèse porte sur la découverte de nouvelles stratégies pour l'activation/fonctionnalisation C-H des terpènes, avec un accent particulier sur le (+)-limonène et la catalyse au palladium. Tout d'abord, nous avons décrit le couplage C(sp2)-H/C(sp2)-H déshydrogénant catalysé par le Pd(II) entre le limonène et des alcènes pauvres en électrons, avec une extension à divers terpènes et terpénoïdes. Ensuite, nous avons étudié la post-fonctionnalisation d'un produit issu du couplage déshydrogénant développé et de l'éthynylbenzène en conditions micellaires. Par la suite, nous avons développé

Abstract:

Thermolysis of Cp*W(NO)(Np)(η³-CH₂CHCHSiMe₃) generates a 16-electron allene intermediate complex that selectively activates hydrocarbons at their methyl groups. In the case of linear alkanes, only terminal activation is observed. This selectivity persists in the presence of an ether functionality, but not of other oxygen-containing substrates such as aldehydes and alcohols. With these latter substrates, oxidation of the complex to Cp*W(O)₂Np has been noted. The existence of the allene intermediate has been verified by two thermolytic experiments, and kinetic studies show that Cp*W(NO)(Np)(η³-

Abstract:

The direct functionalisation of C-H bonds has emerged in recent years as an efficient and atom-economic alternative to the traditional cross coupling reaction. One of the challenges towards this goal is the selective transformation of a particular C-H bond amongst many other C-H bonds. This thesis describes studies on the use of CO2 as a traceless promoter for controlling meta-regioselective arylation of phenols and a separate investigation into an enantioselective arylation of pre-chiral η6-arene tricarbonyl chromium complexes.

The activation of carbon-hydrogen (C–H) and carbon-carbon (C–C) bonds by transition metal catalysts is an attractive strategy to streamline organic synthesis. Herein this manuscript, the two main areas of research are described. Firstly, it was found that a nickel catalyst can promote the insertion of alkynes into the C–C bond of 3-azetidinones and 3-oxetanones to enable quicker access to pyranones and pyridinones in high yields and excellent regioselectivity. Secondly, a rhodium-catalysed pyridine directed C–H bond activation enables the rearrangement of 1,6-heptadienes into bicyclo[2.2.1]hep

As fossil fuel resources become more and more scarce, attention has been turned to alternative sources of fuels and energy. One promising prospect is the conversion of methane (natural gas) to methanol, which requires an initial activation of a C-H bond and subsequent formation of a C-O bond. The most well studied methodologies for both C-H activation and C-O bond formation involve oxidation of the metal center.
