Sulfonyl ynamides are highly versatile and synthetically useful reagents. This thesis details the modular synthesis and use of sulfonyl ynamides in order to access N-heterocyclic scaffolds, such as quinolines and pyrazoles. The synthesis of a wide array of sulfonyl ynamides can be realized via copper-catalyzed amidative cross-couplings or by elimination of dichloroenamide precursors. Additionally the use of Sonogashira chemistry to further diversify terminal ynamides and the synthesis of solid-supported ynamides was investigated. Electrophilically-activated amides can be reacted with sulfonyl ynamides in order to access highly functionalized 4-aminoquinolines. The straightforward amide activation procedure with triflic anhydride and 2-chloropyridine was found to tolerate a wide range of substrates, which allowed for the development of a library of 4-aminoquinolines with ease. Moreover, 4-aminopyrazoles can be prepared by reacting terminal sulfonyl ynamides with sydnones under copper catalysis. However, as the copper catalysts were also found to promote the degradation of the ynamides, a copper-free strain-promoted alternative was developed. An in situ prepared 3-azacyclohexyne was found to tolerate a wide array of C-4 substituted sydnones, producing a mixture of both the 3,4- and 4,3-fused pyrazoles in good yields. Additional investigations into heterocyclic methodology led to the development of highly sophisticated, non-symmetrical and axially-chiral dibenzo-1,3-diazepines, -oxazepines and -thiazepines from simple, commercially available anilines. The anilines were coupled to their corresponding reaction partners via a chloromethyl intermediate and the 7-membered ring was subsequently formed using direct arylation.

The Organometallic Chemistry of N-heterocyclic Carbenes describes various aspects of N-heterocyclic Carbenes (NHCs) and their transition metal complexes at an entry level suitable for advanced undergraduate students and above. The book starts with a historical overview on the quest for carbenes and their complexes. Subsequently, unique properties, reactivities and nomenclature of the four classical NHCs derived from imidazoline, imidazole, benzimidazole and 1,2,4-triazole are elaborated. General and historically relevant synthetic aspects for NHCs, their precursors and complexes are then explained. The book continues with coverage on the preparation and characteristics of selected NHC complexes containing the most common metals in this area, i.e. Ni, Pd, Pt, Ag, Cu, Au, Ru, Rh and Ir. The book concludes with an overview and outlook on the development of various non-classical NHCs beyond the four classical types. Topics covered include: Stabilization, dimerization and decomposition of NHCs Stereoelectronic properties of NHCs and their evaluation Diversity of NHCs Isomers of NHC complexes and their identification NMR spectroscopic signatures of NHC complexes normal, abnormal and mesoionic NHCs The Organometallic Chemistry of N-heterocyclic Carbenes is an essential resource for all students and researchers interested in this increasingly important and popular field of research.

Design of new processes that avoid the use of toxic reagents has been the focus of intense research of late. Catalysis by metals and non-metals offers diverse opportunities for the development of new organic reactions with promising range of selectivities—chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. Furthermore, these transformations frequently occur under mild conditions, tolerate a broad array of functional groups, and proceed with high stereoselectivity. The area of catalysis is sometimes referred to as a ‘foundational pillar’ of green chemistry. Catalytic reactions often reduce energy requirements and decrease separations because of increased selectivity; they are also capable of permitting the use of renewable feedstocks of less toxic reagents or minimizing the quantities of reagents needed. New catalytic organic synthesis methodologies have, thus, offered several possibilities for considerable improvement in the eco-compatibility of fine chemical production. Hence, these catalytic methodologies have emerged as powerful tools for the efficient and chemoselective synthesis of heterocyclic molecules. Key Features: Presents the synthesis of different five-membered heterocycles. Contains the most up-to-date information in this fast-moving field. Covers novel catalytic approaches used in the study and application of catalysts in synthetic organic reactions. Presents new methodologies for the synthesis of heterocycles.
