The definition of Carbon Rich Compounds applied in this as in the previous volume (TCC Volume 196) of this series on the same general topic comprises carbon skeletons with a carbon to hydrogen ratio of 1:(kleiner gleich 1), which ultimately implies all-carbon compounds (i.e. carbon allotropes). The current volume covers modern methods for the coupling - mostly metal catalyzed - of subsystems consisting of double bonds, cyclopropyl groups, arenes, and metal-complexed pi-systems with acetylene and diacetylene units. The resulting structures range from macrocycles, including those with all sorts of linkers between the acetylene and diacetylene units, to conducting polymers and light-emitting materials. Wherever appropriate, chemical transformations of these intriguing compounds and materials are discussed as well.

Carbon Rich Compounds are defined here as carbon skeletons with a carbon to hydrogen ratio of 1:(=<1) which includes all-carbon compounds (i.e. carbon allotropes). The current volume covers modern methods for the preparation and transformation of polycyclic aromatic compounds including substructures of C60-fullerene and novel highly complex cyclophanes. A graph theoretical treatment presents a substitution rule, allowing the description of already existing structures and also the definition of new challenging synthetic targets. In the second part of this volume, the synthesis and unique chemistry of oligocyclic compounds consisting of five- and six-membered rings, so-called centro-polyhydrindanes as well as oligoquinanes, in particular highly unsaturated ones, are discussed.

This current and five previous volumes (Volumes 133, 135, 144, 155, 178) convincingly demonstrate the vast applications of small rings in modern Organic Synthesis. Such applications range from total syntheses of cyclopropyl-group-containing natural products and non-natural biologically active compounds or compounds with other important properties (e.g. liquid crystalline) via syntheses of cyclopropyl analogues of natural and non-natural physiologically active compounds, e.g. peptidomimetics, to the use of cyclopropyl groups as reactive subunits in so-called composite functional groups. This current volume covers a survey of the wide range of biological activities of cyclopropyl-containing compounds, up-to-date comprehensive reviews on the multiple applicabilities of two multifunctional small ring building blocks - methyl-2-chloro-2-cyclopropylidene acetate and bicyclopropylidene - in Organic Synthesis as well as a striking new approach to cyclopentenones from easily accessible 1-ethynylcyclopropanols, which is rather general and favorably complements other cyclopentenone syntheses.
