The compound [Cp′Mn(CO)2]Se2 (1) reacts with primary arsanes and phosphanes, and migration of the carbonylmetal fragment Cp′Mn(CO)2 (Cp′ = CH3C5H4) from the selenium to the arsenic or phosphorus center occurs. Products of these reactions are diselena-diarsetanes (4) or diselena-diphosphetanes (5). During the reaction of arsanes with 1, arsinidene complexes (2) are obtained in very good yields. Compounds
