2-Aza-pentadienyl anions are easily prepared by deprotonation of N-allylic imines. They react with carbonylcompounds yielding 3- and 5-substituted 2-aza-pentadienyl derivatives and , depending on the reaction conditions.

hydrocarboxylation of 2-azadienes through cobalt-catalyzed hydrogen atom transfer and oxidation. This protocol provides a source of 2-azaallyl cation equivalents under mild conditions, is chemoselective in the presence of other C═C doublebonds, and requires no excess amount of added alcohol or oxidant. Mechanistic studies suggest that the selectivity arises from lowering the transition state that leads
