Book Description
This dissertation focuses on cyclization reactions of 1,6-enynes involving ruthenium catalysts. Three different types of cyclization were developed from readily available precursors, such as 1,6-enynes and alkynes. In one application, a novel ruthenium-catalyzed hydroalkynylative cyclization of 1,6-enynes using terminal alkynes as co-reactants was explored. This reaction provides and entry to five-membered rings featuring an exocyclic 1,5-enyne motif. A neutral electron-rich ruthenium complex Cp*Ru(cod)Cl proved to be the catalyst of choice for these transformations. In another application, using the same complex, the ruthenium-catalyzed [2+2+2] cycloaddition of 1,6-enynes and alkynes was developed. Both internal and terminal alkynes were suitable substrates to access bicyclohexadienes with high yields in a single step. An intriguing ruthenium-catalyzed bicycloannulation of nitrogen-tethered 1,6-enynes has also been developed. For these cyclizations, only the electrophilic and alkynophilic ruthenium complex [RuCl2(CO)3]2 was able to perform the reaction. The exclusive formation of 3-azabicylo[4.1.0]hept-1-enes was observed with 1,6-enynes featuring an internal alkyne unit. These cyclization reactions fulfil the atom-economical reactions principle and are discussed on the basis of their mechanisms of formation.

Book Description
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Book Description
The series Topics in Organometallic Chemistry presents critical overviews of research results in organometallic chemistry. As our understanding of organometallic structure, properties and mechanisms increases, new ways are opened for the design of organometallic compounds and reactions tailored to the needs of such diverse areas as organic synthesis, medical research, biology and materials science. Thus the scope of coverage includes a broad range of topics in pure and applied organometallic chemistry, where new breakthroughs are being achieved that are of significance to a larger scientific audience. The individual volumes of Topics in Organometallic Chemistry are thematic. Review articles are generally invited by the volume editors.
