Rutheniumcomplexes of redox-coupled cyclopentadienoneligands catalyze the formation of allenyl carbamates from propargylalcohols and isocyanates. This efficient and atom-economical process represents the first catalytic access to allenyl carbamates, compounds of high synthetic potential. The reaction needs an acidic co-catalyst and can be performed at room temperature. In addition, new (cyclopentadienone)iron
