Ni(O)-Catalyzed Formation of Azaaluminacyclopentenes via Azanickelacyclopentenes: A Unique Nickel/Aluminum Double Transmetalation Reaction

Azaaluminacyclopentenes, which serve as useful precursors for gamma-substituted attylamines, were catalytically prepared from novel Ni-mediated three-component cyclocondensation of an alkyne, an imine, and AlMe3.
