Palladium-Catalyzed Decarbonylative Rearrangement of N-Allenyl Seleno- and Tellurocarbamates

ABSTRACT Decarbonylative rearrangement of seleno‐ and tellurocarbamates carrying an allenyl group on the nitrogen was found to proceed in the presence of a palladium catalyst to afford 3‐chalcogeno‐1‐azadienes. This transformation may involve oxidative addition of Pd to a carbon–chalcogen bond, deca...

Summary:ABSTRACT Decarbonylative rearrangement of seleno‐ and tellurocarbamates carrying an allenyl group on the nitrogen was found to proceed in the presence of a palladium catalyst to afford 3‐chalcogeno‐1‐azadienes. This transformation may involve oxidative addition of Pd to a carbon–chalcogen bond, decarbonylation from a carbamoylpalladium unit (R2N‐C(O)‐PdChPh: Ch = Se or Te), Pd shift, and reductive elimination.
