Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>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.</p> </abstract>
