Nickel Catalyzed Functionalization of Allenes

Over the past few years, nickel catalysis encountered allenes in organic transformations, opening direct access to a plethora of chemical scaffolds in straightforward manner. The activation of allenes or their reaction partners by means of [Ni(0)] as well as [Ni(II)] species enabled chemical diversity and complexity to be achieved simultaneously through desirable concepts like selectivity, functional group tolerance and mildness. An overview of the most recent findings in the area is presented herein.
