Abstract
Recent developments in the chemistry of η3-allylruthenium complexes (synthesis and reactivity) are described. Among different possible preparations, their straightforward formation via oxidative addition of allylic substrates occurs either at ruthenium(0) or ruthenium(II) centres. Subsequent reaction with an electrophile or a nucleophile is the basis of their ambiphilic involvement in catalysis. In this review, we focus on catalytic substitution of allylic substrates by C, N, O and S-nucleophiles, and show that selected ligands make possible stereospecific, as well as regio- and enantioselective substitutions.
Keywords: diallylation, Phosphorus ligands, triphenylphosphine, halide coordination, isomerism

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
