Abstract
This review presents the recent progresses in the transition metal mediated synthetic transformations of heterocumulenes (e.g. carbon dioxide, isocyanates, carbodiimides, ketenes, etc.). Organic transformations featured include cycloadditions, nucleophilic addition, metathesis reactions, and polymerizations. Particular emphasis is placed on catalyzed reactions although in some cases, stoichiometric reactions are also described.
Keywords: isocyanates, carbodiimides, coupling, polycarbonates, epoxides, copolymerization, carboxylations

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
