Reaktionen von Phosphanen und Arsanen mit Diselenkomplexen

Article abstract of DOI:10.1016/0022-328X(87)87106-1

The compound 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 with a P-Se-P unit (6) can be isolated as by-products of the reaction of phosphanes with 1.
