Metalloenzymes are a fundamental source of inspiration for synthetic chemists. Oxidation metalloenzymes catalyze oxidation reactions with high efficiency under very mild experimental conditions exhibiting exquisite regio- ...
Organometallic aryl-CuIII species have been proposed as key intermediates in Ullmann-type reactions. However, such species have long remained elusive and mechanistic investigations of a plausible catalytic cycle remained ...
The physical and chemical properties of fullerenes and nanotubes can be conveniently tuned by the attachment of different functional groups to them. Therefore, the systematic understanding of different problems such as ...
Transition metal-catalysed [2+2+2] cycloaddition reactions involving unsaturated substrates represent one of the most elegant methods in organic chemistry to prepare functionalised cyclic compound. This doctoral thesis is ...
The development of novel catalytic methodologies involving the formation of carbon – carbon/heteroatom bonds to produce cyclic systems constitutes a field of great interest in the modern synthetic organic chemistry. Over ...
This thesis focuses on the study of hydrogen dynamic behavior in a series of proton sponge cations as well as in bis(silyl)hydride organometallic complexes. To understand the dynamic behavior, a new tool, i.e. the ...
It all started in 1985, when Kroto, Smalley and Curl discovered by serendipity a new carbon allotrope. They synthesized for the first time the C60 molecule, and named it as ”Buckminsterfullerene”, because of the similarity ...
The use of self-assembly to bring simple building blocks together into complex product, has led to the preparation of an increasing number of sophisticated and functional 3D supramolecular nanocapsules. By understanding ...
The development of supramolecular assemblies with big cavities is important to recognize specific guests or infer a chemo- or regioselective chemistry, in analogy to natural enzymes. The objective of this thesis was to ...
Coordination-driven self-assembly has led to the realization of an increasing number of elegant and sophisticated functional structures, the structural complexity of which would be difficult to achieve using conventional ...
One of the major current scientific goals is the development of renewable energy sources. An effective alternative to fossil fuels consists in the conversion of the sunlight energy into chemical fuels. The molecular hydrogen ...
