Abstract:

Gold has emerged as valuable tool for chemists. The physico-chemical properties of the metal centre make it exceptionally prone to activate multiple bonds, such as alkynes and alkenes. Thus, its utility in catalysis has been exploited together with the synthesis of suitable catalysts to allow new, efficient transformations, and the understanding of their intrinsic mechanisms. Reported in this thesis are efforts to this goal, such as the design and study of new Au(I) and Au(III) complexes towards functionalisation of alkynes. The development of new catalytic systems is tackled in Chapter 2. An

Formaldehyde is a chemical used widely in the manufacture of building materials. A remarkable example is represented by the Lucite two-step Alpha technology for the large scale production of methyl methacrylate (MMA), the essential building block of all acrylic-based products. Esters and ketones are important intermediates in the manufacture of acrylate esters therefore α-hydroxymethylenation of carbonyl compounds using formaldehyde as a one carbon alkylating agent and subsequent dehydration to the corresponding methylenated derivatives has been explored in the current work.

Concerning the former, initial efforts were focused on the development of a general and straightforward synthetic methodology towards complexes of the type [Cu(X)(NHC)] (X = Cl, Br, I). More than 10 NHC-Cu(I) species were synthesised in high yields under mild condition

The study of normal N-heterocyclic carbenes (NHCs), which probably represent one of the most important families of ligands in organometallic chemistry and homogeneous catalysis, has indubitably led to the usage of other related ligands beyond di-amino carbenes. So far, such species are only marginally used as ligands due to their relative novelty and stability. The following chapters describe the exciting journey into the development of new synthetic accesses of various abnormal, remote N-heterocyclic, mesoionic and carbocyclic carbene transition metal complexes.

Zirconia-based catalysts, in particular sulphated zirconia, gave significant activity.

Abstract The harmful emissions of chlorinated volatile organic compounds (CVOCs) originate only from man-made sources.
