Ruthenium-allenylidene complexes and their specific behaviour
Résumé
This review presents recent innovations in the field of stoichiometric transformations of ruthenium-allenylidene systems via synthesis and at the frontier of material science and catalysis. It especially shows new routes to the first bis-allenylidene-ruthenium and diruthenium complexes, trisallenylidene ruthenium triskelia, the use of ruthenium-allenylidene as precursors for alkenylcarbynes and indenylidenes, and the involvement of allenylidenes in the building of dinuclear ruthenium bridges with a C-7 carbon-rich bridge.
