A series of chalcogen analogues encompassing a ketone and chalcogenoketones [{PC(=E)P}Pd(PMe 3 )] (E=O, S, Se, Te) was generated from a nucleophilic palladium carbene compound, [{PC(sp 2 )P}Pd(PMe 3 )] ([PC(sp 3 )HP]=bis[2‐(diisopropylphosphino)‐phenyl]methyl, i Pr 2 P‐C 6 H 4 ‐CH‐C 6 H 4 ‐P i Pr 2 ). The thio‐, seleno‐, and telluroketone were all synthesized by means of an atom transfer from the respective chalcogens. The ketone analogue, however, required the use of nitrobenzene or nitrosobenzene as the oxygen‐atom transfer agent.
