Abstract
Pyridinium ylids are versatile tools in organic synthesis. The stability of pyridinium ylids and their generation is commented. This review gives an overview of the possible modes through which pyridinium ylids can react. It is demonstrated that pyridinium ylids are suitable building blocks for the synthesis of indolizines, cyclopropanes, 2,3-dihydrofurans, 2(1H)-pyridin(ethio)ones, mono- & oligopyridines, pyranonaphthoquinones, nitrones and azepines.
Keywords: Pyridinium ylid, indolizines, nitrones, pyranonaphthoquinones, pyridines, epoxidation, aziridination, cyclopropanation, olefination, Ortoleva-King Reaction, α-halomethylketones, Photochemical Reaction of α-diazoketones, nitrosoarenes, ketocarbene, oxirene, solvatochromatism

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
